Yaaas, puts me in mind'o ridin' the TAT, back in '14. The first significant water crossing was in flood, and too dangerous to cross. Re-routed with the GPS, and came to another un-crossable ford, so found a route with a bridge but it led to an unsafe ford on another crick. Tried one more time before givin' up and goin' back to an Interstate, and killin' the whole afternoon findin' a way 'round that sucker. Wished I'd had a computer, to get a better view of the map. I'll bet there was a pretty smart way to get 'round that baby. Anyway, I hope your bypasses all work out well . .
