Hey, I have band rehearsal today at 4:30 I am traveling about an hour away first. My car will be in a parking garage for 5 hours first before leaving to practice and its a high of 41 today. Question is, is this safe for my gear to be in the cold that long? I have my strat in a hardshell case and pedals in the PT-1 hardshell case. Should I wrap a few blankets around them?
