Nice collection of commuters, and they all look in pristine condition! The bike forum link I referenced in my prior post has a Classic & Vintage bike forum that may find your collection of interest.
It's amazing how bicycles have evolved over the last 40 years. Heck, just in the 11 years since I purchased my '01' Mongoose hybrid the upgrades available are great for all types of riding.
I always have my bike with me when I go camping
