Might sound like a funny one, but leaving Coniston Coppermines today, my pannier bounced off my bike on a particularly bumpy road, and rolled into the river up by the miner's bridge.
Obviously being in spate, and with several waterfalls close by I couldn't find it. If it does happen to wash ashore anywhere down the river, or in the lake could you let me know.
I could describe it, but I am sure its a unique situation. It is an Ortleib so quite waterproof.
Cheers.
