Is it bad to leave your MD out in the car in this extreme heat or in the really cold weather mines stayed in the truck since I bought it 5 months ago. But today was hot!!! As blazes and it made me think that that's probably not the best thing for it. Does anyone else leave there's in the car 24/7 I like always having it on me incase I get the chance to do some spur of the moment hunting. But what do you guys do ?
