Barton's number BTW is 0161 787 7326.
I'll check the situation out this a.m. (I'm going down there). If this is a problem that is expected to go on into the w/e, they'll be tearing their hair out - It's a Fly-In event there this w/e.
Nearest place for fuel for those coming up from darn sarf would be Sleap, methinks. I have to bring a Citabria up tomorrow (Thursday) for 4 days flying out of Barton so will obviously monitor this.
