I never tried the air or water in my RC adventures, but I will never forget the feeling of elation and power I felt when I first drove an electric powered toy WITHOUT tracks or slots to determine its path. I felt that same sense of overall ecstasy watching my buddy running a brass two-rail Mikado with a quick conversion over my three rail layout. Crawling through turnouts without a care was great--I need more of that.
In the succeeding days I have also remembered the chore that charging batteries had become (of course I was competing in three classes and charged to get the most I could in four minute each four minute run). I do have some concerns about grades and train length on my layout, but that only means I need to play around with dead rail for a while longer.
I think I will overcome the history I have with batteries, but I do not think I can ever settle for swiping on a screen.
