Sponsored by Heritage Montgomery, this year's celebration features 30+ parks, museums, and historic sites open with FREE admission throughout Montgomery County. Activities for all ages include history exhibits & programs, outdoor recreation, children's games & crafts, music, & FUN! Many sites are especially welcoming to cyclists, who can peddle along scenic byways from site to site, and picnickers, who might plan a relaxed afternoon in one spot.
