This app is a good idea but has a ridiculously insufficient database. There are only 289 roads listed in the entire USA....with only 2 routes in Oregon that were worth mentioning apparently.
Now, Im only a novice rider but even I know that is not true.
So although a good idea, this app is about as useful as a septic infection! So pay no heed to the first two reviews and please put your money to better use.
