You can set your GPS for 341 School Street in Acton. From Route 2 East, which is listed as Massachusetts Ave., take a right onto School Street and the field is on your left. That right turn has a 119.6 mile marker sign on a small grass island. If you see a brown unpainted rocket with an orange chute on the power lines it's mine If you see a yellow rocket with a black nose cone and fins hanging from a very big pine tree, that is also mine.
