When I was in Bristol I knew that when I got up to Welshpool on the Offa's Dyke Path I would turn left there and walk around the Glyndwr's Way, a 135 mile circuit through north Powys. Because I didn't want to carry an unnecessary book with me (300 grams!) I asked on my Facebook page if anyone would let me post a guidebook to their address and pick it up as I passed through. It was a borrowed book, from my neighbours in Talbontdrain, the most recent version being out of print and £20 online.
A woman called Debbie sent me her address, I later found out she'd done this after an email from Karen, the woman I stayed with early on in Newtown.
At midday on the day I was due to post the book I received an email from Paddy Dillon, writing to offer me a copy of the Glyndwr's Way guidebook he'd just written.....the bloody book I was just about to put in the blinking post!
Turns out he is a writer who met Hannah and Chico the donkey on their route round Wales last summer and, following Hannah's post about me on Facebook, wrote to offer me his help.
So that's how I ended up using this, the only copy in the country of a soon to be published book. Thank you Paddy and Debbie. And Hannah and Karen. And the strange power of the Internet.
