no, but i've had a moped stolen. Its pretty area specific plus population numbers plus rampant drug use plus mental condition plus economic conditions. If you walk down the street and see everything barred up so not even a hand can get anywhere close to entering a building, turning a knob, breaking a window, etc then u know theres been a long history of thieverie, tenpered glass covering the sidewalks, etc.(like san fran or brooklyn)
I always lock my ped, and cover my stuff up no matter where especially in high crime areas.
So, im in stockton right now, last of the wild wilfd west. This place is nuts, population of thieves-high, drugs-rampant, everything has to be locked down and hidden cuz your stuff will be broken into and brazenly stolen and sold.
On the other hand, if your in Pittsburgh and go to Kennywood (amusement park) you can pack a cooler and leave it at the picnic tables with thousands of others and not worry if anyone gonna ransack it, a total trip.
