When using Google Maps does anyone use the bicycle directions? My rides have bee in upstate NY and Google had horrible directions. There are a lot of State Bike Routes that google doesn't know about and won't send you on. I find the best options so far are to use the car options with 'Avoid Highways' which means just avoid interstates. That puts you on NY State highways which for my experience generally have a great shoulder.

Overall, I navigate by phone. I have a charger and solar panel to help out. I also feel ok leaving my charger plugged in at a state park bathroom outlet for a few hours while it charges. So far I have never run out of battery.
