I don’t have fixed travel dates when touring. I organize my tours so that I can be flexible enough to meet demand but ad sites typically require that you have travel dates listed in order to post.
I pick cities close in proximity to each other so that if one city is slow, I can drive over to a nearby area and salvage the situation. For instance, I can plan a tour in DC but if it turns out Baltimore is spending more, then I’m saying “Screw this city, bags are packed I’m out!”
In summary: When you’re booking PLEASE IGNORE the tour dates on the screen. I go where the $$$DEMAND$$$ is. So pick a date YOU CAN COMMIT TO and I’ll do what I can to accommodate you.
