well 80 outside, can be 100+ inside a car
if you can leave the windows open some, that will help, but its not something I would suggest
I know personally 2 people that had bows melt down, ruined due to being in a car truck in the summer time, and one in a back seat of a buddy's 4 door truck
so??
and if you haklf dry fired the bow when the loop let loose
be a good idea to have it all looked over, that can throw timing off and possibly crack a limb too
and play hell on a srting
so give it a close go over and even maybe paper shoot it to make sure its all trus and good
