If you have access to camping in the back yard you should play around with set ups before making a big purchase if money is any concern. I know my suggestions aren't fancy and take a bit of work but they are proven by folk much more knowledgeable than I and easy enough to try, plus that's half the fun for me when winter camping. My warmest sleeping bag is rated to 40 from a garage sale(more money for knives right??)...and I camp in the COLD...like frozen eyelashes and nose hairs cold and I only sleep in my long johns. minus fifty smifty...you gotta get out even when snow is on the ground 8 months of the year. I know, I know, but for some odd reason I take pride in writing this from the coldest, largest populated city in the world...gotta be good for something??
PS thx for posting this...I can't wait for ice fishing and winter camping now! but I guess I gotta get a deer first...its been a rough fall for bow hunting for me. sorry to ramble, just enjoying the thread with a few beers. Cheers guys! Add pics of winter camping to help entertain me. I'll see if I can scrounge up a few.
Let us know what you go with/try OP
