Paper maps of this are either insufficiently detailed or too bulky, or both. The Google Maps app on my iPhone is outstanding -- as long as there's data connectivity. I also have iTopomaps on my phone, and I have all the quads for the local area downloaded. Since I know the area extremely well and I'm confident in my ability to navigate without any aids, my decision has been to not carry a paper map.

It's a compromise. On the train and on foot I can't carry all the gear that I have in my car all the time. Heck, I can't carry everything in my car that I have at home.
