Took Brownie for a LONG walk, 

during which we found Alex working on the dirt bike track.

Alex talked me into riding, though I stayed far away from the jumps!

A trio of young boys, biking with Mom, rode up and obviously enjoyed watching Alex perform.  After we suggested they try out the track they rode over some of smaller hills and gave their enthusiastic approval.

I'd let Brownie off his leash to explore.  At one point he found the one remaining mud puddle to lie down in, then topped that off with a roll in the dirt.  Guess who got a bath when we got home?
