'E's reet you know (Sir George). Barton's your best bet. Haydock Park racecourse has an E-W strip, but very much PPR & usually only on race days. There is/was a microlight strip up near Blackburn somewhere. Not sure if Rawtenstall Lumb i still open these days but as you said, it requires nerves of steel. plus transport to Chorley is probably impractical.
I'd take Barton while it's still there! The coffee is quite nice too these days.
