Yes there would be interest for feminine GFE TS's in Boston.  We have far too many good looking TS's who don't deliver top flight service.  Add in the crap shoot that is the visiting TS scene and the market really is under served.

I was there last week, and went to Jacque's on Tuesday and Wednesday. First night was a bit slow, rained and there weren't many girls out at all. Second night got busy around 10:00PM and by 11:00PM it was really hoppin. Most of the shemales were a bit bizzar, but there were a few really sexy ones. Some good black, and a few Latinos too. Just have to get up the nerve to take the plung....... Could have had 3-4 obvious dates, but I didn't like their feminine quality....it just wasn't up there, or, maybe I just didn't have enough to drink....

Cai;
    Beware if the agency is INTERNATIONAL SHEMALES.  There has been much negative experience related on SER.

The tgirl scene in Boston is sorely lacking. If you could find attractive girls with little/no attitude, you could probably do well here.
