Welcome. The next 6 or 7 years of your life will probably be the most fun/challenging/difficult/exciting times you may ever have and it would be wonderful if you could document it on film! And, you are not likely to ever have as much free time to explore something like photography so get to it and good luck! You will find some amazing resources here.

I lived just up the road in Ossining for a few years in the early nineties and have some fond memories of Tarrytown. Saw a few gigs at the Tarrytown music hall and enjoyed learning about the history of the area. I am gradually sorting through and scanning all my film negatives and recently came across a few from that part of the world.
