Visiting Hay on Crutches or in a Wheelchair

I came across a blog at seenobounds.co.uk, written by Jamie McAnsh, who uses a wheelchair and crutches to get about. Recently he visited Hay, and gives quite a positive account on his blog dated 16th July, though he adds that the hills, and steps into some of the shops, make things difficult.
And on 30th July he wrote about the trip he made to Tintern, which he also enjoyed.
