Yeah I got a flat in Burlington. Had stopped for the ride safety meeting and it just spontaneously gave out. *shrug* nothing in the tyre, the spare tube inflated OK, so I dunno what happened.
Pics from the ride (crappy cellphone pics):

Looking out to the Burlington skyway from the Hamilton-ish side (North Shore Rd)

At the Beach park area at Lakeshore/Lakeshore (right near Joseph Brant Memorial Hospital):

And where I stopped for the meeting, and got the flat - this was looking back over at Hamilton/the Skyway as I was somewhat down the lakeshore, but still in Burlington somewhere.
