Now, the large majority of you on here will already know what I'm about to say, but this is for any novices... or halfwits, like me!
'When you get a puncture, always check the inside of the tyre for any sharp, pointy thing that caused it before putting a nice, new inner tube in.'
I know some of you will be shaking your heads knowingly at this point and... you're right to. A puncture on my way to work and then a puncture on my way home... same wheel... same culprit. Fortunately, I managed to repair the first puncture at lunchtime, and remove the offending thorn on the second 'take' so avoided a long walk home.
On a brighter note, my brand new, 'never-been-used' pump works and I got some good puncture repair practice in. Every cloud and all that...
And if the young guy who kindly offered his help outside the WoL Visitor Centre is on here, I appreciate the offer, mate. Thank you.
