Dub,
Horham is active, operated by Andrew Castleden (sp?) who is a farmer and flying instructor.
Give Old Buck a call this morning as a) he may be there and b) they will certainly have his number. It may be listed as he sells tree plugs to arborealists. If you can't find his number let me know - I shall be at leics sometime today and I'll phone a tree surgeon chum.
However, if he is unable to help my strip is a lot closer to his than any other. So you can always speak to me.
