Echoed in most parts, but some updates on the current state of the pubs.
The White Hart is definately the one to go for in Stockwith, for food and beer.
If you stop at Clayworth (Retford and Worksop boat club) You MUST eat at the Brewers in the village, it's superb. Be warned though, you do need to book. The other pub in the village, the Blacksmiths Arms, is currently closed. The boat club is open Wed, Fri and Sat evenings, and lunchtime Sunday. You will get a warm welcome and the beer is criminally cheap.
The Boat at Hayton wasn't very good in the summer, which was a shame because it used to be ace.
The Hop Pole, and The Gate, are currently closed, though work is going on at The Gate, so it may be reopening soon.
In Retford, I can highly recommend the "Rum Runner" Great real ale pub with a good atmosphere.
It's a shame the notice is so short. I'm taking Helena from W.Stockwith to Clayworth on Saturday, on my own. You could have joined me for the trip!
