Actually, I believe the likelihood of anything truly malicious is very very slim, but it's better, in my risk-averse book, to be cautious. A more likely event, I suspect, is the sudden arrival of a bunch of rowdy and hitherto unknown musicians on your deck at an inconvenient moment, who just happened to spot your boat and decided on the spur of the moment to drop in for a drop or two and a jam...harmless, but potentially unnerving.
Anyway, enough about posting boat names--I never meant for it to get so involved. People should do what they're comfortable with.
I'm hoping my festival guide comes in the mail soon, and I'm waiting to hear about buying concert tickets from the US...Reynaud and I are counting the days! We go to festivals here, but Middlewich seems a lot more interesting than anything we've been to, what with the "fringe" and the boat gathering. We really have no idea what to expect except that we're pretty sure there will be WAY TOO MUCH to see and do and hear.
