Beg to differ there w/ ya @Six30.... finally woke up to some of the white sunshine on the Deck today....pretty wet though @ 32F, it didn't stick around long....
As uncooth as it might be....patios usually have a concrete floor, but Decks have a floor of wood or synthetic lumber....especially when the floor is 3+ft. off the ground...
My new helmet is in at the local bike shop. Just need to get off my ass and drive down the mountain to get it. It's a bit of a drive at 65 miles away, so I'll wait until Saturday msot likely.
Might beg them to install the Cardo unit while I'm there.
