I've never really had much in the way of weather delays. The closest I have had was when I broke an axle fifty miles east of Redding CA. It took most of the day to get it replaced which put us heading towards the coast out of town on a Friday afternoon. After my wife was very nearly smeared against a cliffside by a flatbed truck, we gave up riding and just walked on the other side of the road. Apparently it was less fun to drive close by a bicycle whose rider wasn't astride it. That is, the eastbound motorists gave us a lot more room to walk than the westbound ones gave us to ride. After about an hour or two of this, we came to a junction with a smaller highway and got back on the bikes for a wonderful trip.
