Let’s see, where can you go next? Brochures on Paris, cruise down the Rhine, and travel the U.S. - Looking at those National Park videos did get you excited. Maybe an R.V. for the U.S. travel? The fall is a great time to see the leaves turning. But when you traded travel stories with one of your friends, Bill, he said that the best way to see the world is fly/bus/tour guide, which got you thinking. It’s not much more expensive, less driving is probably better, and there’s never a worry about carrying your own luggage. Several of the daytime tours consider time/heat/if your knee hurts.
You called a travel agent and ask about the trips Bill mentioned. She said she would get back to you with some choices. When you received the information, you were excited. You can do this! How about October in Maine and Christmas in Florida?
