I got a flat tire about half way to work this morning. I had to do the "walk of shame" back to the house pushing the bike along the way. But it was only a 1/2 mile walk. I then got on the old Raleigh mountain bike and it was on the road again.
I have read about inserts you can add in between the tire and the tube to help prevent punctures. Since the road bike has such narrow tires that looks like the thing to do.
