The mosquitos are really bad right now in our city park, so when I went to play yesterday, I wore a cap. I'm not normally a cap wearer, but my head is the only place I can't really protect with bug spray. I found out that I can't wear a cap while I play, at least not when I drive. The bill always seemed like it was in the way, though really, if it were, I've got serious form issues. As far as the Deet goes, my son works outdoors at night, and he uses Deet constantly, and he notices his skin burning after a while. He also melted the paint off his Itouch cover after handling it with Deet-covered hands.
