These are my "Guide Books" from my trip in the 1980s! Some people may not consider park maps a "freebie" but I LOVE looking at old maps or guide books. It's amazing to look back over the years and see how much the park has changed! It also helps when looking at old photographs to remember which attraction you were riding.
So, grab one free map as you enter the park(s) to use during the day. On your way out of the park, grab another free map. Keep this one for your scrapbook or keepsake box. That way it's not worn, folded and wrinkled!
