Hmm, yeah... I know that I thought about Oban, and in places like Fort William, you'd probably be sorted. Two years ago, we were up in the North West - Ullapool etc, and there's plenty of stuff going on there. But to be honest, I've had a look fr stuff a couple of times for you, and I'm not turning up all that much in that area. I'd try the local tourist office, they're getting a bit mre switched on to these opportunities..Sorry can't be more help...
Ironically, there's more happening session-wise in the bigger towns ( I think)
Cheers
