Edit: After reading several articles written by veteran chasers I have come to the decision to only chase with other more experienced chasers until I get more experience. I do not want to be labeled as a yahoo chaser. I'm just not confident of my abilities just yet. For those who haven't read these articles I suggest you do. Very good info in them.
