TOD - I remember riding the wooden carousel at Great Falls of the Potomac during my family's mid-1950s visit to Washington, DC. Apparently, the carousel was destroyed in flooding brought about by Hurricane Agnes in 1972.
I'm not a big fan of amusement park rides, but have fond memories of Disneyland and Universal Studios. We were there in 1996 and had great fun on Pirates of the Caribbean, Indiana Jones, Star Tours (twice!), the ET bike ride, and the Jurassic Park flume. At Disneyland we rode in the front car of It's a Small World, Richard singing at the top of his lungs. Rob (age 11) was mortified.
