A lot of local FBO's don't have CFI's who can fly with you every single day, 5-7 days a week because it's not their only job. I used to live in the southern MD area, and there was really only one flight school thanks to the ADIZ. I know the school redbaron is talking about. It's hard to get a plane often up there...such as 7 days a week.

There is absolutely nothing wrong with learning through a local small FBO, there's many advantages...but depending on your area, it is hard to get in every single day.
