Lewis and I had similar senses of humor. I think any hobby that doesn’t provide some fun and a few laughs now and then probably isn’t worth the time and effort you put into it. Lewis and I were on the same wavelength. Like our "McDonald’s hacks." We found out how to modify a two-meter radio so we could make our voices come out of the speaker where customers placed their orders at the drive-through of a fast-food restaurant. We’d head over to a McDonald’s, park nearby where we could watch the action without being noticed, and tune the handheld radio to the restaurant’s frequency.
