You are so lucky so have seen sunlight - when I visited last (in August) it chucked it down constantly on both our visits. Still is a pretty impressive place though.
Am hoping for less inclement weather this weekend.
I took all my credit cards with me, when we went to the visitor centre, expecting to buy the whole shop but only bought Gerlad Ponting's book and a couple of prints, in the end.
