After hearing about the heat and not wanting to burn baby burn, I headed to CVS to stock up on my sunscreen. I really like to sunbathe and don't want to risk being unprepared.
I upped the level to 30 SPF to deal with the 100-110 degree days that I spent in Phoenix. I would have brought it from home, but TSA prevents you from carrying containers larger than 3 oz. and aerosal cans in your carry-on bag. Fortunately there seems to be a CVS in every city I go.
