Welcome!
have lived here most of my life, like all places some good some not so good but I like it! Agree with most of the suggestions so far, Hornimans great, and the green chain walk is fab fun, most recommended 'specially the woods (see if you can find the folly!) - fab! Also must recommend The Capitol for obscenely cheap food and drink in pretty decent surroundings, go there most weekends for brekkie. I see also that there is a guided walk this weekend, I think that might be a fun way to get your bearings.
Hope you are happy and enjoy your new place
