Go to any park and have a picnic, walk or bike around too, chestnut ridge/emery park/letchworth and etc.
Wine tours in the southertier (Chataqua County), great to do in the fall, see all the foliage, and you can taste wines all day for practically nothing. Its also a great way to find your tastes in wines if you are not certain what you like.
Find a private spot along lake erie on the beach and chill out there. 
Go for a drive in the fall to ellicottville to check out the leaves, and walk through the shops.
In the winter go sledding, Chestnut ridge… more money=skiing, or tubing at colden tubing co.
