Ya what King said.

I route all the protected Zones, Area Zone (like area 1,2,3....) boundries and the Canadian border. I then store them in my computer I put them in different folders so I know what folder to upload for what area I am going to be fishing.. I use digital charts to make all my routes on PC . When I know I am going to fish an area, say around the canadian border, I just upload all important waypoints and Routes. I love digital charts and the computer.

P.S. Dont go out and buy the brand name chart engines the dont work with alot of G.P.S. systems.
I would recommend using Ozi Explorer. It is by far the most universal Digital chart engine. It can upload/download routes and waypoint to almost all G.P.S. systems. Ozi Explorer
