Have you tried Aaron Brown? He's fairly local (Donny), he's a good rider and he does a bit of park riding. Check out ontrials on fb.His brother's decent on bmx as well so he might be down.
Did you return the allen keys when you couldn't figure out how to use them and demand that your mate pay for the repair? Then when he said "no that's completely ridiculous", did you start a dispute thread about the whole thing?
I liked it but started to get bored halfway through. The editing was good and I can appreciate the level of riding but my attention span is just too short.
71 Telford St. You'll need bolt croppers for the shed. I'm not sure which door or window would be easiest to get through though. The wifes in a lot as well so it'd be hard to recommend a good time.
