We are using ours to chart the trails in our local region and mountains. We want to eventually set up a website so that other riders can contribute their rides and you can upload/download and share trail rides with others. I particularily love that you can put in special sights and stop overs. Also, you can note technically difficult areas.
It is our greatest trail riding toy! Absolutely love it and wouldn't dream of going without now.
I'm glad I found this forum. I have a website (www.trailmeister.com)that does exactly what QtrHorse mentioned. Presently the horse trails are confined to Ohio (just waiting on better weather to hit the trails in our new Seattle home!). Besides bridle paths I've got hiking and mountain biking trails mapped in five states.
To keep accurate data I use a survey unit from Trimble. It's accurate to under a meter.
Thanks so much for the opportunity to share!
Thank you very much Vidaloco! - Check out the what's new section - I just added videos of a couple trails here in WA -(no horse trails yet though) and knot tying. BTW- I just read your post on rattlesnakes. Very scary. We didn't have them in Ohio, but from what I hear they are here in Washington. I hope I don't see any!
