Since it's that time of the year, I thought it would be a good idea to start a discussion about different experiences or techniques we use that relate to brumation. Hopefully we can help one another avoid common (or uncommon) problems (putting them in, taking them out, or even keeping them in brumation). Here's an example:

I used to brumate my snakes in my heated garage. It worked fine for a few years, but one time in the late fall the temperature in the garage was in the mid-50s (~13C). The outside temperature was in the upper 30s (~3C). I raised the garage door about 1/2-way up to reduce heat loss while my kids were running in and out of the garage to play. Within about 1/2-hour, the temperature in the garage dropped to about the mid-40s, and I ended up losing two of my brumating snakes. This example shows that brumating snakes are very vulnerable to sudden temperature changes.

Pass along whatever advise that you think might help someone else out.
