I think y'all put some kind of hex on me. After saying I've used the crossover method for years, and not having any problems....on the way down to Moonshine, I had my bag, stuffed with old fluffy military sleeping bag....just to rest my back against....strapped on seat. Thinking my mirror was out of adjustment, it dawned on me I was about to lose my bag. Just barely made it into a lot before it fell off. Came loose once more in Mattoon too. On the way home I changed it over to parallel, and didn't have any more problems. Can't figure it out.
Isn't that the way it always works?? ;-) BTW, Mattoon was my old stomping grounds when I was a young man. Grew up in and around Windsor (farm) and Mattoon was where we hung out, etc. LOL
