Let’s call it a cultural experience. This afternoon Luke and I went to “the historic OK Corral Indoor Arena” (aka, a big barn) near Harrah to watch dirt bikes, hot rods and souped-up go-carts race around and around a mud track. There were propane heaters and Frito chili pies and gas fumes and cigarettes and camouflage. Luke loved every minute of it. And it’s just a warm-up. Tomorrow: monster trucks.
