Hey gang, looking for real-world advice.
My 1st nice cue is due to arrive in a few days, and I want to make sure that I'm taking care of it as best possible. (Nuthin fancy by forum standards, but a couple-hundred dollar McDermott that I'm pretty excited to get. That's a big deal in my world!) My problem is that I work 35 miles away from home, and often have to go wherever I'm going to play, without the time to go home to pick up my cue. Thus I need to leave it in my car. I'd really rather not have to take it into work with me, and risk forgetting to take it with me when I leave.
Understand, I fully realize that temperature extremes are bad for cues. I get it. What I'd like to ask everyone here is what their real-world experience is with leaving their cues in their cars.
I live in Maine. It gets pretty cold in the winter, and for a couple of months in the summer it can get quite hot and humid as well. I guess I want to know how cold is too cold? 50 degress? freezing? Zero?
Similarly, how hot is too hot? 70 degrees? 80? 90? When it gets hot here, it is usually quite humid, not that fabled "dry heat" I hear about...
Have folks wrapped their cue case in a blanket and avoided trouble? Is there a style of case that is designed for these issues? Or perhaps an insulated box to put the case in?
I'm just a newbie in this pool world, hoping to tap the collective brilliance of the forum and maybe learn something, without having to learn it the hard way.

Thanks in advance.
