I think 'Museum' is not an appropriate word, 'Exhibition' would be better. When myself and a couple of mates were over this year for the S100 we visited the Jurby exhibition and there were two coach loads of 'tourists' visiting and seemed to be enjoying themselves. I think it may attract visitors to the Island who see it as an additional experience. You would be surprised the number of non-bikers who visit, was sat in the Douglas railway station waiting room and overheard two guys who had come over only for the trains ! Not everyone is skint, I always do TT and S100 (and occasionally the Manx) in the same year, as do my friends.
