Not me, I’m working til 6pm. There’s three USAF KC-10’s, a C-130 and a KC-135 in today. I think they’re leaving around lunchtime to refuel some F-15’s going back to the states though?
As for the rush hour, you’ll not get too stuck as you’ll be coming off the M77 onto the M8 just before the Kingston Bridge, it’s slow but it keeps moving and you’re only in it for a mile from that point. It’s quieter anyway just now with the absence of school runners.
Of course you could always take the A81 between Kilmarnock and Edinburgh ?
