3 tubes and you are out.
I know, I know, we aren't supposed to discuss flats .... but . . .
Bicycling on a new- to me - trail with unmarked cross streets, I went down the sidewalk a bit to see a cross street sign (in case of an emergency it is kind of nice to know where you are) - there was a cement abutement to my right.
Turned the bike around to come back - at least 12 goatheads in EACH tire.
OK, I had two tubes with me, found a bench and fixed the tires. Of course the old tubes were not of much use, each containing at least five leaks. While fixing the tires, my water bottle fell of the bench and broke.
A mile down the road, "thunk, thunk, thunk." The front tire was not seated correctly. Let the air out, reseated, and pumped again. However, the entire valve core blew out during the pumping process.
Called the "rescue wagon" who smilingly came and retrieved me.
I wanted to go 40 miles, only went 21!
This is the same trail on which I got two flats the last time. I think I will find another trail!!
Sorry, just had to vent.
