My son & I went camping with his troop at the end of October and again in mid-November. Both were cold enough to be considered winter camping (40-45 degrees midday, below freezing at night), but there was no snow in the area at the time.

It actually rained the second night of our November campout - the rain was frozen on the tents in the morning. My son had left his boots outside his tent. You live - you learn.

I find that my feet get cold at night. Maybe its an old age thing as I didn't have this problem when younger. I've tried two different mummy sleeping bags - one by Marmot rated to 15F and another from Cabelas rated to -20F. It can be brutal if I don't put wool socks on before turning in for the night. BTW, I really like the Cabelas Summit bag though it is HEAVY compared to the Marmot bag.

Last March (and again this coming March) we camped in a cabin two wood stoves. Those stoves make a huge difference temperature-wise. We had lots of snow outside, which was fun.
