Is anyone familiar with a ride mapping program or website that will overlay convenience store (etc.) locations? DH and I have done unsupported centuries before, but they were in areas that we knew reasonably well, including where the gas stations and C-stores were. Now I'm looking to branch out a little further, using routes posted on sites like RidewithGPS.com and Mapmyride.com. But these are some rural areas and I can't safely assume that there's going to be a place to get water on the ride route.

Is there a way to do this in a Garmin Edge 705? I looked and couldn't find it in the settings menu.

Many thanks in advance!
