GoHunt and OnX both have their places IMO. GoHunts maps for me have been extremely laggy and hard to use since they came out. As an OnX user since the beginning I prefer their maps and system paired with Google Earth.
Sounds like you're on the right track! Do your research and be careful not to get in over your head. An elk is not a small animal to be killing 10's of miles deep without proper prior planning. Good luck!
