Forget the course, I'm in Bristol. For £300 per man, per day and I'll take you out and train you up
I'll even show me around my van, (2 man set up) and show you my backpack, have a go and see what you think....
In all seriousness, find someone within a reasonable travel distance to you that may be willing to show you the ropes and how their system works.
I took someone out a couple of years ago (think he was from dorset somewhere) that had been on a 'training course' as he wanted to get a grasp of it all in real time. With all due respect to the chap (I'm sure you're better now if you're still on the forum!) the training course he'd been on was a waste of time. Trad and wfp, they hadn't shown him much about much....
