I have the ACA map for the northern tier and it's not bad, but I supplement it with Google maps if I'm following the ACA route for where I want to go. Google allows you to sort directions by mode of travel and bike is one of their modes. So whenever I want to go somewhere I take a print out of the directions and print out of any area I need to zoom in on for more detail; but I use Google exclusively when the ACA map cannot be used for the area I'm going. Google map is also being updated all the time but it has a lot of bike paths and lanes across the US marked out. Google does not have off road paths that I know of marked.

Google is easy to use simply click on directions, put in where your starting from in the A column then enter where you want to go in the B column. You can also click on any road on the map you want to start from and click on any road where you want to stop. Google will try it's best to route you on a designated bike path or lane, if it doesn't or you know of one it's bypassing you can drag your route to that area and it will recalculate a new direction. You just need to play it with. Google lacks specifics like camp grounds, bike shops etc, but if you know what route your taking you can preview the are before you go and find places like that and then either mark the location on the map via a pen or have your mouse pointer activate that spot on the map. Like I said just play with it.
