Elvington is on the list to do, I've been there by road, great place and caff. Fenland, yes, apparently according to the plate their caff is open on Wednesdays, only about 20 mins from me. I set off there last month but had RTB because of weather, I must give it another go. Sherbourne tank museum, must look that one up, sounds interesting.
Breighton is good, but no hot stuff except weekends. Didn't know about the pub though. Sherburn has a good caff too but I've been there a few times.
