TTGL, I live down here in FL and am able to MD all winter as so far in my life we don't have too many cold cold days, but in the summer it's !!!!!!!!! HOT !!!!!! But just don't forget to take your battery packs apart. I read on another TNET thread that some guy's had to buy new battery packs cause they forgot. Even if I know that I'm not going to MD for over 3 or 4 days I take mine out of the tector and as with my BH ID Itake the batteries out of the pack. Also my cordless headset and the x-mitter on my MD. olegator
