This gentleman spent about 2 hours answering all of my daft questions about the surrounding area and the Roman remains. He was working as a volunteer for the local wildlife sanctuary and spends his time wandering around checking out the sites and answering questions (and asking people to keep their dogs on a lead). He was a very interesting and informative person and did not seem to resent sharing his time and knowledge with a passing stranger.
Chesters fort was the first of the English Heritage sites I came across. This gentleman introduced the fort and gave me lots of useful information about the site. One of the most impressive things about the walk was the museums and historical sites maintained by English Heritage and the National Trust. Each site had things of interest, and was manned by people who were polite, friendly and knowledgeable. I ended up getting a 9 days overseas visitors pass which was brilliant!
