I'm not trying to be a wise guy, but if you just earned your glider rating at that airport, shouldn't you already be familiar with the area? If not, you should get back with your instructor and have them familiarize you. I understand that you may not be 100% up on the routings of jets in and out of the area's airports, but it seems to me like this would be something important to know if you're operating out of that area.
