Paul just a thought, with practice at the TT now being limited would it not be a good idea at looking to move the traditional dates for the TT. By moving the event by two weeks daylight hours would give an extra 30 minutes practice. During the last two weeks in June it does not get dark until after 10pm some 30 minutes later than in the beginning of June, an extra bit of practice would go a long way in the issue of safety.
The Island does not have to worry about the traditional tourist dates now as we only get the tourist during the racing so it should be easy to move the event. Not only that, June is not a traditional Holiday period in any other country, most places have set holiday weeks, ie factory shutdowns.

As I said only a thought of mine.

Admin, maybe we could have a poll on the dates issue to get some feed back
