Motorcycle Crash

So, um...yeah.  Did you hear the story about that family whose kids kept breaking their bones?  You know...arms, wrists, fingers...  Breaking them so often that their name is well-known within the ER?  Perhaps we may have another chapter to add to that story.  Yes, our little dude Michael broke his thumb today.  (Siggggggghhhhhhhhhhhhhh.)  How did he do it?  Well, ever since he became obsessed with motorcycles, he has gained a new sense of daredevil never shown before.  (C'mon, this was the kid who wouldn't go down a slide until he was about three.)  Since he doesn't have a motorcycle of his own, he has adopted his ride-on toys as motorcycle stand-ins.  And, he shows no fear when riding them.  (See video above.  And, please note that this is not the incident in question, in spite of the spill at the end.)

Today, at one of our favorite playgrounds, he started taking his jet ski ride-on down a rather steep sidewalk toward a big concrete area.  I only let him go halfway up at first, and he had to demonstrate to me that he could apply his foot brakes at will.  He was executing everything perfectly and with caution, so I finally let him zoom the whole way down from the top.  He was in such heaven that he must have done it at least 100 times.  Unfortunately, a group of older kids joined in, with a lot more reckless abandon than that which I had previously drilled into his head.  Once he saw them going down the hill as fast as they could go, he had to do it, too.  Unluckily for all of us, I had moved on to tending to Neve and didn't see his derring do skills.  Lo and behold, I suddenly heard him bawling and holding his hand.  I have no idea what happened, but the thumb must have taken the brunt of the fall.  Poor little dude.  He chose Daddy to take him to the ER, and all reports show that he was so brave and never cried at all.  We have now drawn a motorcycle on his temporary splint and await the real cast.

So......does anybody have any suggestions on what to do with a kid in a cast at the beach?
