I can only speak from my experiences in Madison so please don't take this as the way it is for everyone as different ladies can have different experiences in a city.  Years ago, I did visit Madison on a regular basis in spite of many of my fellow providers warning me that I will get mostly- cancellations and not make much money.  I didn't get many cancellations and when I did, the gentlemen had enough respect to let me know in a timely manner.  This is NOT a problem for me as life gets in the way sometimes.  My annoyances were the large number of young men (18-25 years old) begging me to see them even though I don't see anyone under 30; Constantly begging me to lower my rates, unacceptable texts and e mails and, the final straw, 4 different young guys lied about their age.  When they showed up, I sent them right back out the door.  One told me the DMV made a mistake and his age was wrong on his license, another told me that he thought I would go ahead and see him if he showed up.  I don't appreciate the games and manipulation some of the youngin's there.  These experiences are similar in most college towns for me.

With that being said, Madison is a great way to meet gentleman who travel for business.  I have met some great gentlemen there traveling through.  

The way I handle this situation is to offer out calls only there for a minimum of my 90 minute rate.  This covers the travel and I don't have to worry about all the nonsense mentioned above.

After a while I get a feel for a city I visit and sometimes I make changes in how, when of if I visit.
