We picked a bad place to do it and dragged our loaded bikes over hundreds of yards of deep sand. Unfortunately we were using a particularly sticky lube at the time. The brakes, chain, and dérailleurs were loaded with sand. We spent a good bit of time cleaning the bikes up at a nearby water spigot in the State park we were in.

The whole thing was a fiasco, but now it is just a humorous memory. On hindsight I would have picked a different spot or just carried the wheel to the water.
