After reading this thread, I thought I would share my "bunny-hopping" onto the sidewalk, while instructing DH and children (10 & 12 at the time) to "WATCH MOM DO A NEAT TRICK!!!"story.

I accelerated across the street, aiming for the sidewalk, approaching at an angle on my new mtb. Apparently, I did not lift my front tire off the street and onto the curb as planned. I flew over the handlebars and landed on my chest (cracked a couple of ribs) had the wind knocked out of me and...my "evil" spawn were laughing their heads off. DH was sincerely concerned (he's my favorite.)
To this day, my kids almost cry with laughter when retelling the story of their mom showing off.
That was my last bunny-hop onto a sidwalk. I stick to 1-2" distance now.....
