by the way juamei, it's supremely irrelevant, but the other week I visited a spring not far from there (near farmborough) and it was really cool, so if you want to trudge out that way I'll tell you where it is.
I would also suggest that if we walked to Stoney Littleton from Bath for the grand sunday event, that would be interesting, but I can't swear to what I'll be doing that day (plan ahead, me, hmm)
