[GarterGuy]

I haven't brumated any garters yet (they're all too young and I only brumate if I'm going to breed), but I know my L.m.thayeri were down for over 4 months and did ok. I usually don't like to go past two or three, but I was delayed in getting their tanks set up so I left them down an extra month plus. They came out ok and gave me a nice clutch of eggs.
