personally i dont trust maps, i like to get out and find food, water and beds before setting up a good spot, a map only shows so much, you need to be there to see natural funnels and such, you could find a good spot on a map and get there to see its blocked or all brush, you may be off by 100 yards, then waste the day finding a better spot when you could have known all that by not looking at the map, as far as general idea? fields, cover? ridges? etc...
