Ray, after you rest up, let us know if you think the rain and wet conditions somehow caused your battery to fail (seems like it should have lasted longer than that (I'm really not a fan of battery tender, just ride often to keep things charged like a car, I replaced last fall a Harley battery in my Springer which was new 2000 I think and no tender, Lasted 8 years! ).
Glad you made it home OK (the old body knows when it's stressed)! We gotta ride together soon (maybe next yr for Redwood, Run 21, or sturgis) JUST order up some sunshine!
