Hi suitedservitude, I think you, me and maybe Maximus92 should suit up and get muddy! get in touch and lets arrange something and Minion12 bring it on mate - lets get covered!
Ideally I'm looking at two locations, firstly the River humber at low tide is soft, super sticky and seriously good fun, I have three different play area with differing depths from 5ft to 2ft depending on everyones likes. The other location is a silted up lake next to a wildlife reserve although there is another venue but its best explored after hours as its within the grounds of a private estate.
