Be sure to read my travels in my blog and post your own.
Travel is a great way to learn more about the world. You can always take a guided a tour but my preference is to just go and explore. Sure, you may miss some things but then you will also discover a lot that you won't find in a guided tour.
One of my goals has been to travel Route 66 (rather, what's left of it) from end to end. Route 66, also known as the Mother Road, is a great part of American history.
Cruising is the way to go if you want to see several areas and don't want
to be packing and unpacking all the time. A great place for information
on curising can be found at Cruise
Critic.
