:) If you're not on your own, or know other people on the Rugby Club campsite who also want to 'session hunt' on the Friday it would be reasonably cheap to share a taxi into town, the fare would be about £5 or £6 ( not too bad divided between 3 or 4 people) but probably double that if you're returning to the campsite after midnight.

For anyone just wanting short,level stroll followed by a drink there's
The White House , Upgang Lane, YO21 3JJ, next to the Golf Course. Don't think they've anything Folky on but it's the nearest pub to the Rugby Club :)
