Keith probably drove Al through the medical way the most, it was something that made Al happy-- so why not.
( We would wonder what the people in the building thought if they saw us .)
Then one day Al asked to go the medical way and as we drove through and out the other side, the other exit was chained off so we could not drive through anymore. It was so disappointing to Al and us. Apparently they didn't like us driving through their lot and blocked it off. It stunk, we were no longer able to drive Al through the medical way, we felt so bad for him.
Again, it was always the simple things that made Al happy.
