Can you confirm that's June Ross? I'm not saying I can't do that weekend, it just means I would have to change things round as regards to servicing my car and getting it ready for the trip. But I'll go around everyone else.
If the plans are to explore the local area a little more, then why can't we do that during the day time, then when the track's open late afternoon/early evening, then we can go on track then. It gives us more flexibility as regards to when we go, and saves us hanging around waiting for the track to open.
If people are not happy to do what I've suggested above, they don't have to drive during the day if they want to 'save themselves' for going on track later on in the day. And surely if we all go places together, we only have to take 2/3 cars - there's no point putting all the cars on the road; not really practical imo. Maybe the people who aren't planning on driving on the track later on in the day can drive to places during the day?
Just a thought...
