i live in south oxfordshire..i dont know any local ones personally..cant offer you advice on setting one up,but somebody else will maybe..sometimes,it isnt difficult too do a ghosthunt on your own..as long as you have the basic equipment, emf,camera, digi voice recorder,cam corder then you should be fine too do it on your own..i always find things happen when your not lookin and when you least expect it..wouldnt mind doing oxford castle with a good team..was it good night when you went..?
