Two holes in the right tyre this morning, hopefully I got enough of the thorns out of the tyre to prevent repeats.
Then on Commonwealth Ave I was presented with three entirely unsatisfactory options:
a) Try to mount the very high curb to the left.
b) Veer out of the bike lane into peak hour to the right.
c) Run straight over the broken stubby in the middle.
Option c) made for some very interesting noises...
I don't think any glass got stuck in the tyres but I'll check again before heading off this evening.
