Scooter gas jugging! WOOO! Full tank in 2 minutes! Damn, I almost traded my Subaru for a Honda dual sport bored to 700cc rather than 650cc, but the person proposing the deal was a liar and I kept the Subaru. Good luck busking, I don't know what places are ideal. Maybe outside coffee shops? places where you won't get kicked out?
Oh wait! I do know good places! Traffic medians! I would busk on traffic medians right next to intersections and local cops never had a problem with it. However, on a state highway, state troopers would be bossy and kick me off to avoid a liability. Traffic medians are great though, just don't get hit. People were throwing money at me while driving by, and when they would stop at a red light, I would be right next to their driver window so they could hear me. Vehicle traffic moves faster than foot traffic too, so you don't have to have as much material but stay aware of ALL of your surroundings and DON'T GET HIT! duh. I would make $25 in about 5-15 minutes, gas jug, which took longer, and then hit the road.
