Access details such as terrain (rocky, grassy. beaten earth, tarmac etc), slope, distance, gates, steps and other obstacles, nearby parking (essential) are more use that a Yes/No system which is too simplistic.
We know that the Ancients did not always think of access for disabled people when planning sites! These days people have become a bit more inclusive, we hope.
Thanks for all the thought that people are putting into this, this is the way that society should be...
