I love Whitby Goth Weekend! Been going for about 5 years now and it just keeps getting better.
Unfortunately our daughter was too young to leave with grandparents for us to stay for the weekend this time so we could only go down for the day on Saturday. We still had a great day though. We dressed the bairn up in a misfits rompersuit and a black woolen cardigan so the whole family was dressed for the occasion. It's an amazing sight to see an entire town full of goths/punks/metalheads/etc.
We love it there so much, I proposed to my partner there and we will probably hold the wedding there too.
