Hello Mike, i understand where your comin from, but its a route that get used all the time, the roads aren't that bad, roads in Scotland are good, fair enough the motorways down south might be busy but its no big deal.
The gumball 3000 across america goes through New York, me and my girl freind was their last week (IT WAS FREEZIN, 28" OF SNOW IN 1 DAY IT WAS CRAZY), the traffic their is chaos, there's no way i would chance drivin a £250G motor through that, but they still do, another thing Chris Moyles is doin it so it can't be that shit of an idea
