In reply to joe.91:
I know it's easier said than done but I'd make the effort and go somewhere beyond the UK. Unless you're careful, long stretches of time (ie. several months) become increasingly hard to find as you get older, so if you get the chance, I'd take it now. You'll have plenty of time later to do stuff closer to home.
I travelled/climbed round the US mainly alone for a year (back in the 80's mind, so things may have changed). There were plenty of other dirtbag climbers around to hook up with in popular areas like Yosemite, Joshua tree. I would have thought it would be easier these days with the internet - you could set up partners before you even head out there by posting of climbing sites. You tend to find as you meet up with people things develop from there - people offer you places to stay, jobs, places to go, and further people to hook up with. You've just got to put yourself out there and be open. I've done similar in Europe - it's closer to home (but sometimes that just makes it easier to bail out and come home), and there's loads to go at. But on the other hand it's all easy to get to for short holidays. I bet Canada would be good, especially if you're into mountains/winter, but don't know what it's like for hooking up with people . Can't comment on Australia/S.E Asia.
