Rolled out Sparky (the tadpole trike) fully intending to ride the one mile to the Interurban trail (on the sidewalk, if I had to) for an easy spin, but I couldn't do it. Two houses down from mine, a truck pulled up and suddenly started backing up, and I freaked out, and turned around and went back home. At least I did establish that I could readily sit down and get back up from the low seat, and that the bumps in the driveway didn't hurt the ribs too much if I went over them slowly.
