I think the first one will be in T&W, if only because the majority of members seem to be from the area.
I will try and identify a location that is easy to get to using 2 or more operators as well at this stage.

If it takes off and there is enough interest to take it into Co Durham , Teesside or Northumberland - I am happy to hide the envelopes elsewhere.

Suppose that is part of the challenge as far as my role is concerned.
Finding locations that are suitable and convenient, coming up with clues which have the potential to mislead/confuse and making sure the envelope is hidden somewhere which isn't going to cause the issues you mention.
