I think that in 100F the only place where you really can be happy is on or in some water. So that last one looks "soothing" (now that you told us how hot it is) - we start to melt here and complain about "the incredible heat" when the temps only start nearing the 90s! And I doubt we've actually had 90+° ever so far this summer (but we are having a beautiful summer!!!)
Did the profile pic of your son turn out? Did he look like himself in the end?
LaFoto - Yeah, the heat was oppressive yesterday. We eventually found the water rides, the log flume being one of them. After we got soaking wet from the water rides, we were much happier. ~ I tell you, the portrait only looked vaguely similar after it was done. It only cost like $15 bucks and she just took like 10 minutes to do it. But, it made for good memories of the park that day.
