"Perhaps its time to consider the Manx or even more Norn Irn
racing?"

Come for the Manx, Mike. Classics (well - replicas) thrashed in anger, pre-65 two day trial, a much bigger Vintage rally than the TT can accommodate (join the VMCC, get a suitable bike and you can take part in the closed-roads run)

I have always rated the Manx fortnight higher than the TT - the right crowd and no crowding.

PS bring your thermals, it's a few degrees cooler than June
