Has This Ever Happened To You In The Summer Time?

Since triple digit temps have hit the Basin as of late, it reminded me of something that happened to me years back that was pretty dumb on my part. I used to be bad at 'living out of my car' and had my entire bathroom in my car at one point, including a can of aerosol hairspray. NOT SMART!  

The thing exploded in my car and was all over my interior causing the biggest mess for me to clean up and reminding me that I should never do that again. It's no secret that summers in West Texas are scorchers and nothing should be left inside for this exact reason. I remember my friend freaking out when her soda can exploded in the same way as my hairspray. I doubt we are alone in doing this...what have you left in your vehicle, that you learned the hard way not to leave again?
