You can’t visit historic Boston without walking the Freedom Trail. There are plenty of options of how to follow the trail. Guided walking tours with costumed interpreters are very popular, you could join one of the famous Boston Duck Tours if you don’t fancy walking or if you want do it on the cheap you can do a self guided tour. We did this option as it gives you the freedom to spend as long as you want at each site and it’s also free! Yay music to my ears.
The Galveston Duck Tour is a unique way to see Galveston Island. On the Duck, you'll travel 40 blocks on Seawall Boulevard - overlooking the Gulf of Mexico to Offats Bayou, where you'll then enter the water for a cruise across the bayou! http://www.galveston.com/ducktours/
