I'll be 75 next year too, and I don't plan to quit riding for many more years. I've given up using the bike as a commuter, as there are too many aggressive, or distracted drivers on our busy freeways. But I'm keeping it, and using it for Patriot Guard Missions, and a few casual rides to find interesting places to video. Your videos have been an inspiration to me. I bought a GoPro, and now I'm learning how to use it, and how to use editing software. Watch out YouTube, Daddy Dave is coming!
