I do this in my head while driving. I try to name plants in the medians, peoples' yards, the surrounding areas. Any name goes as long as I know it's correct. It's a fast game or slow game depending on how fast I am driving. It's a good brain twister! Sometimes, I amaze myself at how many different plants I can ID. Other times, I am tongue tied and get stumped. Like those Old Fashion Roses...Vintage Roses...I never came up with the name before I passed it! And that's the rule, you gotta name it before you pass it. A lot of times I see things I don't recognize. A lot of times I need to keep my eyes on the road!
