on saturday i was riding my hardtail mtb parallel to a set of big long stairs in front of a municipal building and decided to try to climb the stairs by riding up one by one, while still going parallel to the stairs. i got to the last stair (10 or so) and as i was about to make the last hop to the flats up top, my rear tire got caught on the top stair, at which point i froze and instead of dismounting i tried to ride out of it but ended up tipping over sideways and falling all the way back down, tangled in my bike.
no falls on my fixed recently though.
