Nice vid, reminds me of my last mtb tour of Scotland based out of Killin. Managed to plunge my right leg deep into a bog on the first day of riding and was dumped with the nickname bog foot for the rest of the week.
The vid highlights the benefits of a good local guide, while it can be fun to find your own way, you may miss some great trails and you will find the crappy ones.
Time for plan a return trip for maybe 2015.
p.s. brakes don't have to squeak in the wet, either the wrong pads or poor maintenance.
