Now is a great time to start researching what will be going on in your community for summer family fun! Many communities host 'Music in the Park', or 'Movies on the Lawn' or 'Theatre in the Park' type events for families that are free. These are wonderful opportunities for your children to experience theatre and music at a great price: FREE!! Check your local papers or call your local chamber of commerce or tourism office.
Many National Landmarks host great art events for families in the spring and summer---any that are surrounding you are great ones to check!
