ya, im in calgary.
we used to rip some parkinglots and small parks in the NE but the bylaw officers finally caught up with us, but we got away with warnings.
if your dead set on ripping parking lots you could try in the foothills industrial area after work hours, or on weekends. lots of big empty parking areas with little to no traffic. take a drive around there and see if you find a good spot.
or you could do what everyone does and go to the Blackfoot moto track. there is a mini track there and its 15$ to ride all day. mini-moto races tuesday nights
Wild Rose MX
that is the website for the blackfoot track.
