Yeah you dont have to worry about "safety" in Madison. But you want to find a good place thats free and you wont get a ticket. I agree with mike, street parking on a saturday should be ok and you dont really need to be anywhere in particular if you have scoots to ride. I would say avoid the far east side for parking and the distal south side, but even there its unlikely anyone would touch your car. Anywhere in a 10 block radius of scooter therapy should be safe.
