Ah, a kindred spirit. I didn't have a map pouch on my handlebar bag when I did part of the Northern Tier, and I can't read without my glasses, so every time I wanted to check the route I'd have to stop, get out my map (from under the camera and wallet and energy bars, etc.), find my glasses (from under the camera and.....) and find where I was and where I wanted to turn. Then I'd have to fold up the map and remove my glasses, stuff them back in the bag, get the lid of the Ortlieb handlebar bag to close (anyone else find this a pain?) and ride off, only to repeat the process a few miles down the road.

Oh, and did I mention that, in spite of the excellent ACA maps, I still missed a couple of turns?

I think I'd like having a GPS take care of all this for me.

I guess I'll just have to buy one and try it out.
