Huge congratulations,here's to your next thousand! 

Just been reading all the posts and looks like you have some great ideas. If all is well with permission etc,would a possible schedule like this be something like we could organise.
1. A morning cache walk of say 5-7 miles for anybody whose interested roughly between nine and one.
2. A picnic for say an hour and a half when we return also selling raffle tickets etc.
3. Then set off on a nice multi on the woodland walk for about two miles which then children could be involved in,and also showing other normal non-caching visitors to the park about caching,who could possibly tag along to learn what it's about,promoting caching etc.
4. On return,finish off with more geochat,raffle draw and farewells.

Sorry if something like this has been mentioned before and i have missed it  ,and i don't mean to tread on toes,it's just ideas that i felt like contributing. 
Did you Wrighty do something similar which was popular like this Bidford way with Mel and Judi a few years ago?

We will be at this event,so see you there
