Recently started bike riding again -- back problems prompted me to purchase a used recumbent. It's a Haluzak Horizon and very comfortable! Gimmie another two months and I'll be hanging with you upright roadies.
When not doing a road-ride, I use bicycle to tow a kayak to local harbor (5 miles.) Found a few towing systems on the web, but they were all either too expensive, too heavy, or attached to seat-post (which seems scary) -- so I made my own out of (mostly) cheap materials (see pic.) Pic shows my hard-tail which towed yak about 15 trips, have since mounted hitch to recumbent.
Am a professional LabVIEW programmer (when employed) but right now having way too much fun riding, paddling, and fishing.
Thanks for tip re: frequent rides in Oceanside - have been keeping an eye on posts to Southern California forum since. Probably I should read "Socializing for Dummies" before actually participating.
