Even on the regional board, you will want to privide some information on your preferences.  Appearance, personality, services, in/outcall etc.  There are far too many variables, so you need to narrow down your request.

If you don't have VIP yet, it is a good idea.  That way you can research and get a better feel for the ladies you have narrowed your search down to.

Have fun!

Check the regional board for where you live or where you are traveling and do a message search for top providers.  Others have already asked these kind of questions, and see who is mentioned.  Then check the reviews on those ladies, and go with who you like best.
