Mmmm... Got me thinking!
We have severe water restrictions at the moment, which means I can't wash my bikes without risking a hefty fine, or using just a bucket. Now, if I had a squirt bottle of degreaser, liberally coated the bike with it and headed off into such a creek, perhaps it may do the same job!
Excellent photo, hope he got out without drowning the electrics!
