Spot played out so he was trying to decide if he was going to reclaim the dig or have a little more fun. He decided to turn it into a BMX track for a bit. 
That's my boy!! I'm not sure if the hole digging or the track is more dangerous. After spending several hours on the track with him racing around, I now know......The track! 
He is really good at it!! I can keep up pretty well.... I only biffed it 3 times.
Once I landed right on a cactus. 
Track is a blast Tim, good job!! Here are a few pics of him on his track.Click to view attachment
