Anyway, doing the cultural tour by bike seems a great idea (said she, never having biked in 'Ull before). And it doesn't really seem worthwhile to find a bus for a fifteen-minute tour, does it?

Dave Bryant - yes, I'd like to borrow one half of your spare tent (actually, both halves might be called for ...). So, thanks for the offer. Does it come with transport to and from the campsite? And, as I said earlier, I'll bring my own sleeping bag.
