In reply to andymac:
I also have an admission to make .
After puncturing on Monday night , I sprung into action.
I was being watched by 2 elderly campers ,and must have impressed them by having the new tube fitted in jig time .
I then began showing them the CO2 gas and pump and proceeded to try and inflate the tyre.
Problem was that I forgot to unscrew the Presta valve.
Result was that the pump hissed and then blew itself apart ,complete with a jet of ice cold CO2.
Think the old timers must have found it rather amusing.
I got a lift home.
Honesty and Transparency.Always.
