Directions: From either direction from I-495 take exit 30 (2A/110) and turn toward Ayer (that's to the NW). From either direction, you will make a left turn onto Rt 2A. Follow 2A all the way to the Devens Commerce Center entrance. You will go through a rotary about 5 mi from I-495. Continue on 2A which is the second exit in the rotary (straight across, just past the McDonalds). You will then go about 1 mile and be in the center of downtown Ayer. 2A will take a right turn just past the main business district; there will be a Mobil station on your left at that corner. Travel about 1/2 mile. About 3/10s of a mile after Dunkin Donuts (and just past a power transfer station), take a left onto Bishop Road. After the cemetery (on left) go through the first gate. About 1/2 a mile after this gate, bear right at the 'Y', then turn right at the 4-way intersection, and proceed up the hill, through the gate. This will take you on to the site.

Stop at the gate to sign the waiver and get a wrist band.
