Debra, I used to do parking enforcement.. I also had license plates in my head for years. Nice to know I wasn't the only one. I also used to manage nurseries and would look at lists of plants from growers all the time. There was a time I could drive down the street and name every plant by it's botanical, and common names.. Now it's "oh yeah... I know that one... just give me a minute.. it starts with a C.. or maybe an M... hold on.. it'll come to me...."
