Congrats man, you will get the bug. Snetterton is a great place to start, its nice and big, plenty of opportunity to overtake. The back straight means you can speed test, the bends are not too bad either, just have to watch for the rippling of the surface caused by the cars. Perhaps you could write a full report about the day? It may inspire a few other track virgins to get out there and have a go.
Well done on your getting your first trackday under your belt. Snetterton was a good choice of circuit to start on. Its often less congested than other circuits so you can concentrate on what youre doing and where you`re going rather than all the riders scrapping with you.
