u can also simply ask; find a group that rides/trains together who are at least one level higher than u, and ask them if u can tag along...unless they are squids, it should flatter them. ---and if they ARE squids, then why would u want to?
riding with faster people is THE way to learn...nothing else even came close, for me...and thats still how i learn; we learn off each other.
before you go do lessons i would grab a video camera and have a buddy tape you, you guys could take turns taping eachother. then go home and study the tape, it is very easy to spot and correct your mistakes that way, i know me and my friend have improved dramatically that way.
take a look at donnie hansens website dhma.com it looks like he has a school your way in july. he is an excellent instructor, he dropped my lap times 15seconds in 4days, really a great teacher.
