Love curbs. My main spot growing up was a super low insanely waxed curb. The drill was to roll at it, throw whatever the hot impossible variation, pressure flip or other gross flip trick of the day was and see how you landed. The curb was so waxed anything would slide. The tricks were so wacky and out of control you never knew if you'd get 50, 50-50, lipslide, etc. Fun times. Also love bank to curbs/low ledges.
