I looked at what other events are going on this month and picked Sunday the 27th July meeting at the Mill pub at Elstead (post code GU8 6LE) at 10am to 10.30am. I picked that date as it seems to be empty of events down south and after I checked the Highway Agencies website I found that there's no work going on either so it should be a clear blast.
However, as I live about 80 miles away other than the tunnel I have no idea what else is around there (i.e Pubs for food, good driving roads etc) as just driving up and down the tunnel 5-6 times (inc passenger rides if possible) "may" get a little boring

Here's a map of the general area so you know whereabouts in the UK the tunnel is.

Once again, apart from the date which I can't move (work stuff), please feel free to pitch in with any other ideas!
Cheers.....................................Ian
***EDIT*** Changed the Meet starting point to The Mill at Elstead post code GU8 6LE, same meeting time 10.30am!!!!!
