Occupying in the cold will be hard and dangerous! I would like this discussion to build on the current list and become a survival handbook. More important than the common sense is the “perception” that you are occupying the park through the winter. Divide into groups of three and maintain 4 hour shifts. Keep the tents in place but don't sleep in them. They will provide shelter from the elements. Keep them lighted at night as if occupied by several people and a lap top. Be creative with your leaving and entering the park to avoid revealing your shift change. Don't great your fellow occupiers on your arrival and departures, remember you haven't gone anywhere and aren't going any where. When you aren't on stage for the whole world is watching, seek shelter and sleep. We called it “crashing” and if your are considerate of your local neighbors, you might find couches and spare beds available to you. You must treat your body well, because you are occupying for three. It's OK to run this sham on the man, after all, he ran one on you, and it will help morale. You will also find the the cold effects people differently. If the cold does bother you, help the person with the chattering teeth. TACTIC: Use one of your electronic gadgets to record the audio when you have a large group present and play it in the background when you are doing a live feed with fewer people. Combined with your bloody awful video will allow the perception that your numbers are strong.

HEADWEAR
Wool hat and multiple wool socks. Wool wicks moisture well and the socks should be rotated to bring the wet to the outside where is will dry. Some Navy surplus stores sell the north sea version of a watch cap with a second fold that pulls over your face with eye holes. Heat loss through you head must be avoided.

FOOTWARE
Do not wear sneakers or other shoes of fashion. Rubber boots or a surplus item know as Mickey Mouse or felt packs is the arctic choice. Extra felt packs would allow sharing the outer boot with others. Leather boots are good until they get wet.

UNDERWARE is against the parts you value. Avoid Nylon and Spandex . Cotton is the logical choice and maybe two. I use to cycle in Central Park in the winter and found that panty hose worked great under by legwarmers. The down side for us guys, is they really mess with your leg hairs but are cheap enough to give a try. Thermal underwear is yours to research but again avoid Nylon and Spandex. My personal preference is Carhartt because they have extended cuffs on tops and bottoms and are sewn inside out with seams are outside to avoid restriction of blood flow and all those marks on your skin. Regular thermal underwear might improve if worn inside out.

COATS are for most of you an identity thing and I've been there done that, but you might want to put them up til spring. Down is the best if it is very cold but if not, you sweat and walk around with it unzipped. A down vest is better especially if it has the longer back to keep your kidneys warm. Layered clothing with a nylon windbreaker or raincoat on top that provides both protection from rain and wind and helps with the wind chill factor is the more practical solution.

TROUSERS should have a larger waist size to allow the additional layers worn above to fit. Nylon rain pants or slickers keep you dry and also protects from the wind chill.

MITTENS are warmer because your fingers touch each other but dexterity suffers. Gloves offer dexterity but each finger is surrounded with cold. Both is best and give a chance to dry the other.

BATTERIES also need protection from the cold. If you plan to use a car type battery, choose a deep cycle Marine battery instead. The deep cycle battery can be discharged more and will charge back to full strength. It also has screw terminals and car terminals making it easier to use. Get the two piece battery box which contains the battery and makes it a two handle carry. This equipment is used to power small boats that use electric trolling motors.
This battery, if connected to an inverter will output 120V AC. Attach a plug strip to the inverter and you can use the power adapters that came with the laptops and other coal powered gadgets. I see they just took your generator. A battery charger in another location or parked auto can recharge the battery. Cold reduces the charge in rechargeable batteries. Keep your hand held devices close to your body to keep the battery warm. If you have extra batteries for cameras and laptops, the same applies.
Wheel chairs use this type of battery...are wheelchairs allowed in the park?
Does the Medical section have a valid and legal reason to have such a battery?
