Layer up! Wear two pairs of socks,two layers on bottom (like long johns under jeans),three layers on top.A coat,gloves,a hat.You could also get those warmer packs to put in your gloves or shoes.You will be on the lake and it ll probably be windy so be prepared.
You sure you don t want to watch it on TV? They re gonna LOSE anyways.......For practical advise, I think B probably has a good answer there. For your feet, try finding some of these Newwool socks, they are great for sitting around in the cold. And get one of these seat cushions that sort of warm up when you sit on them (no electricty or anything, not sure how they work)
