Better yet, if you plan on visiting a certain city, read the boards there.

Fuck, this ain't rocket science.

Goddam brain surgeons. Buy 'em books, send 'em to school, and they still fuck it up.

Tell you what. Give me your money and I'll get you laid. Just tell me what want and I'll drop her off.

Fuck.

If she lives in a large city such as Los Angeles or NYC, I would agree she should disclose that information. However, if she resides in some small town or state, it makes much more sense to disclose what state she is in.

I totally understand a provider's need for security...  however it's hard to guess where one is located.  Sometimes the review will have it in the second location column.  Other times one might stumble on it in an ad or by checking the particular edition of the ad site.  
One provider I have reviewed is in a small town...  Reviewers have listed a nearby city, and a number of small towns around her actual location.  That is close enough to decide if you can get to her.  
IMHO, ladies should give some idea of their location.

I agree with the OP. How many times have I wasted time tracking down locations (sometimes from TER reviews) only to find out it's no place I've been to or will be?

Of course, it goes without saying the portable phone numbers make area codes worthless for location purposes these days. Include a nearby big city or region ... something. (GPS coordinates!)

Caveats:

I do not discuss rates over the phone so, I need get the information using some extraterrestrial perception which I don't have one handy.

So I go with wad Benjamin's and lay it on the bed and say, take what you want? How much of a wad?

My picture is 110% real. Not even close to 10%.

No bait and switch. That's exactly what you are going to get you moron

Call me I am waiting to hear from you and no phone number. Extraterrestrial perception again.

There are lot of funny things in an ad. The one that takes the cake is:

I am college educated and I have two masters degrees and 10 spelling errors on an ad with 10 lines.

those who don't list rates...so unnerving
