Greetings everyone ..... I have a tried and true 2610, and I've used it on paved routes, and it works fine .... But I'm trying to find if there are any gpx ? - files out there of forest service roads. Me and a friend of mine are planning an 80% dirt ride in Oregon. It's about 300 some miles one way, and the dirt sections are all forest service roads that are numbered. I can get paper maps of all of it, but I'm wondering if I can get anything for the 2610. Thoughts, opinions, suggestions anyone? G.
