I thought I had a pretty nice map collection......until I met Rhonda Lynn and her DH......she's got her's way more organized than mine that's for sure.....it's kind of funny because I seldom meet anyone with the same kind of passion for maps as I have. She does and it makes for some interesting conversation for sure. I keep waiting on another invitation to ride with her and her DH so I can see what she's added to her map collection.
Rhonda Lynn, we've got a campsite reserved the last week of September at Cataloochee in The Great Smokey Mountains National Park....and space available....consider yourself and DH invited.....
To answer your question, I have a couple of hand helds, a Garmin etrex Hcx, and a Garmin 60csx.....Mapsource is the application I use on the computer, and the Topo is The SE United States Topo, and both can be downloaded from gpsfiledepot.com
at no cost. I tie one on my horn bag and the other on DW's saddle bag.....
If you get a chance, a good high level map of the area is National Geographics Trails Illustrated for Big South Fork. There again, Rhonda Lynn probably has a couple of more she'd recommend....as again, I'm humbled by her collection.
One other thing...If you ever watched the movie "Alvin York" staring Gary Cooper, there's a scene where Alvin goes to Kentucky to visit a bar......that part of the movie is true to life and most of the area to this very day is dry. This isn't an issue for me, but it is for some so if you want an adult beverage then you'll need to bring it with you.
Again, take your time, enjoy the ride, get off and walk if you need to, but above all, have a great time and stay safe.
