this is in Maine, so I imagine somewhat chilly? Maine's about as North as you can get and still be USA. I believe there was mention of green leaves, so I would assume it's chilly, not cold. I wouldn't know, I live in California, we don't have seasons, we have Sun, More Sun, and F*CKING SUN!
Though...this does beg the question, how will all of you not freeze to death in a lake?
Potion, duh
But for reals as a transplanted Yank (now living in Texas) I can assure you that as long as you aren't being a bitch it's survivable. Though this does bring up other questions about how to go searching in a lake but I might as well ask those IC. Speaking of which, when did you guys unilaterally decide Daniel was Batman?
