Gorgeous lake with a full walk around loop and options for partial shorter loops. Gravel walkway so don't wear white linen shoes. Japanese gardens are only open certain hours. Lots of squirrels & geese so bring feed if you plan to have them come close to you. Most houses around lake are quaint and are an enjoyable part of the experience.
Fourth of July celebrations - lots of vendors and carnival style rides.
Halloween they do trick or treating with vendors. *Note-not a line so don't wait behind others or you'll only see 5 vendors in an hour (5 pieces of candy in an hour). We all love our grandma's but no one wants everyone to go at the pace of the slowest person in the group. Go at your own pace having your kids go to to the vendors without a large group and you'll have a good time. Some seem to think it's supposed to be a line and get very frustrated that people don't move fast enough/being rushed by the people behind them. The kids get discouraged with only a couple candies and no one has a good time. It's not a line, break out of the "line" and you and your kids will have a blast.
