This Sunday, October 28th, The Grove will celebrate Halloween. We went to this event last year with the kids and they enjoyed it.
This event is a popular one, kids, and some adults too, come dressed up and take part in various arts and crafts. Oh and of course there's trick or treating too not to worry, but really we found that most children we more interested in all the fun to be had. Get there early is the best advice I can give you. If they run out of candy you can always head to Farmers' Market right next door for some treats for the kids.
In addition to the Halloween activities there will be a Wreck-It Ralph booth set up, most likely on the lawn, so check that out as well.
