There are trade offs to both the OnXmaps app and GFP app, I live here and find that I use the OnX app way more because I can desk scout and preload waypoints, features, etc. I have had no issues viewing walk-in areas on the OnX app in off-line mode. Have you looked at the SW corner of SD south of the Black Hills at all for your trip oTrexGray?
That's great to hear, cause I'm a huge fan of OnX. Plus I'm familiar with it so I should have an easier time with navigation. & I've done a bunch of reading on it and from the information I've gathered it says there's probably a better population of deer in the Hills with less quality bucks and more hunters. As in the NW having less population, better quality, less hunters. Correct me if I'm wrong because I'm only going off information I've collected over the internet and I know that can sometimes be misleading. That's why I'm here talking with all of you!!! LOL
