I finally made Sydney learn to make 180 degree turns in the street. So now I can sit on the driveway as she goes down the street turns and comes back. Repeat. That is much better than riding around the block 100 times a night.
However, tonight I finally got Kim out there to take a ride. Figured they would just go around the block but they took the long way around and Sydney had to show her all the cool stuff she can do — from riding over speed bumps to tackling the dirt trail!
