I don't have any gps problems that couldn't be solved with a 5 pound hammer.

I think they are getting better now that there is real competition.

My permanents seem to attract people that don't have gps'es. On my gravel 200k, I strongly recommend one, the forest service road signs are intentionally put back in the weeds so they aren't easy to see. Maybe it's so they aren't easy to run over, I don't know. But most of the people that have ridden that ride did it without a gps.
