How can you tell it's summertime around here? Well, beyond the onset of 90+ degree days whose monotony is broken only by violent thunderstorms? That would be the annual Sand Castle competition in Galveston, which is taking place tomorrow. Castle building begins at 10 AM, judging at 3 PM. If you're thinking about heading to the beach this weekend, that's as good an excuse for going as you're likely to get. Via Stina.
