I went to Caernarfon at night and it was really neat. I took some slide film there. I took some color IR shots at Harlech (was going to take b/w IR too, but had some technical difficulties, i.e. film leader didn't catch :'(). I took some normal color slides there too. I'd like to go back. If you get a chance to go up into the turret, do so, it's an interesting view. Lots of stairs though. :o Portmeirion is also a neat place. The television show called The Prisoner (I think that's right) was filmed there in the '60's.
