Last night's meeting with Marc Churchill of Gravity went well. The designs he presented were good although they were for only 1/2 the available area. He's going to put plans together for the rest of the area very soon.
The core group are meeting with Russ from Maverick next week, so things are progressing.
The next stage I think, is to get planning permission for the park (shouldn't be a problem apparently) and get some funding.
