Is mapreading skills, or at least, that's what it seems to me.
I can understand urban camping in a place like Portland, which is so homeless friendly we have private charities helping out and open emergency shelters when it gets cold. But Palo Alto is no place to be homeless- and if you really find the city's ban so offensive, why don't you look at a map and park your RV just beyond the closest city limit? Better yet, why not move to a national forest where your right to camp is guaranteed?
I think there is significantly more to this guy's story than meets the eye, and he needs to learn how to read a map, not how to program a smart phone.
