I waterproof all my maps. Either with a liquid application or contact paper. I do like Adventure paper. I will have to try MyTopo. Never used that.

Not only do I use the standard maps, if I am going to be in a National Park area, I research other trail guides for maps and route specifics, copy them and carry with me.

If I know where I am going to be hiking I put a 'handrail' on the map so if I get lost I can head in a cardinal direction to a safe place or logical S&R area that runs the length of my trip like a road,main trail, train track or river.

I also leave a copy of my map with someone so they know my route.

I love using alcohol based map pens and mark up my maps before and during my trips.

Man, I need to get a new map for my collection.
