Larry, I know just what you mean. I worked for Union Pacific for 7˝ years. Throughout that whole time my residency never changed (they paid Maine taxes) but I was on duty for 3 months and got two weeks off. It was brutal, but after that long you just got use to traveling.
Now that I have been at home for 3 years straight, I find I get the itch to travel every few months or so. Just a raw need to travel.
Other aspects of those 7 years have stayed with me. I still eat at restaurants all the time. No matter how expensive the hotel room, I find them to be all the same, and to this day I must look at a product to see where it was made. Most of the time, I have been to that city.
I think its just Spring. Its the season to refresh and I think deep down inside we all want a new start.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
