Head to Scotland mate. I'd love to get up to Kinlochhourn, It's a 22 mile dead end road with passing places which takes you to the end of Loch Hourn (unsurprisingly) I've been but not fishing. Looks like deep water & the mussels you can collect at low water are massive.
Do everyone a favour if you go though, bring all your crap out with you. When I was there it was quite badly littered with empty beer cans, rig packets & general scruffy anglers crap!
So if your'e reading this & didn't clean up after yourself, you know who you are. Mingers.
