Only slightly off-topic, but I've got a question:

I've heard of 'pub rides', but living in a small town, I've never been a part of one.
What are they, exactly?
Is it a casual group ride from bar to bar, or is it a more 'serious' ride that just ends at a bar?
Or both?

We have a fairly large beer festival in Durham every October, and I was thinking of organizing a ride
in conjunction with the festival this year. I don't know how many people around the area would be into that...
