there is so much poor to bad advice in this thread it boggles the mind. I don't want to get into flame wars so I'm not going to drone on correcting the huge variety of mistaken advice I've read, instead I'll sum up my thoughts with the idea that anyone planning on any form of winter camping is wise to ask for advice, but their entry into winter camping should never be an actual multi-day trip. By the time you are planning on going out for several days on your own you should no longer need advice. You should know your bag works at any possible temperature range you're going to encounter. You should already have experienced any storm conditions you're likely -or unlikely- to encounter. You should already know your batteries and backups are sufficient and your clothing works 100%. You should already have repaired a flat tire in the coldest temps you'll be riding in and done it while it's snowing and blowing at 30mph. You should have done all this and more, preferably with an experienced companion or in a series of baby steps on your own. If you don't do all that...if you just take off on your own with the intention of doing a week of winter camping based on forum advice I don't expect you'll die, but the odds of having a fun, relaxing experience are on some asymptotic curve approaching zero. I do wish you the best of luck regardless of whether you head out with adequate personal experience or not because you may be exception to the rule. Best of luck and hope you have a blast regardless of my concerns. Congrats on the attempt !
