Very keen to come and watch the last round of the season!
Always a problem of course: Off nightshift but fingers crossed (for you ALL) on the weekend.
The A1 North from Dishforth currently has a fair bit of 50mph limit and two lanes due to roadworks and 'upgrades'.
So a bit further but here is an alternative route:

I'm sure you guys are all very well kitted these days but if anyone needs help or anything (minor) brought to the circuit, I'll try to help.
