Do you know about CanadaAdultFun (CAF)? Alot of the more reliable ladies in Calgary advertise there and there is also a big review list from all the members. You can find many reviews of the ladies from CAF as well as BackPages (BP) ladies. It's a really good source to go to for reviews of not only the women that advertise on CAF but also of the BP women, since so many of the ladies that advertise on BP can be scams or poor service. You will need to register first but it is well worth it.
