I’ve been using BikeGPX to help me fill in holes in my Ride San Fernando Valley project. It’s free, and it works well – unless I make a crazy route that keeps doubling back on itself. The it gets confused and I have to nudge it back on track. But for any normal cyclist trying to ride pre-planned routes, it’s a pretty cool thing. Worth having!
The other “use a map to plan a route ahead of time” issue: Did you know that roads and maps sometimes don’t line up? It’s true! It’s almost like the city is constantly changing or something.
But even with glitches, the southeast valley is starting to fill up.
Heck, in a couple of years I might actually finish this thing!
