Thanks guys! I'm going to try tying and see how it goes. I drove him today an Holy Moley was he hot. Hubby drove him first, then I took over. He tried his old "scoot" maneuver today but I knew it was coming. He was trotting and scooted forward into my hands and I brought him back with my elbows soft and dropped and he came back and set his head and strutted . Like Marsha says, my toes curled a little. It was an interesting moment, how his forward momentum was channeled into collection for those few strides.
