What do you do on Vacation??? Or have you ever taken a vacation? Some people like to sit under a tree and read a book. Other must be partying with 100's of other people on vacation.
Set a goal to see every national park or state park or museum or attend every music concert in the country.
I like to simply be alone with a good view or good book.
No mater how small the town you are camped near by, there is always lots of local culture to enjoy for a few days -- like view the world largest ball of string or volunteer at the local ?????
One couple I know travel the country working with Homes for Humanity. He and his wife had worked all their life in an office and wanted to work with their hands not their mind. Now he and his wife are very skilled carpenters -- every few months they learn a new building skill. They are now working to become electricians.
