At the cache coordinates there is a kiosk where you may pick up a brochure of the park, its amenities, history and a trail map. If one is not available, there is a display of both sides of the brochure. And, if you want to research in advance, the map is available at www.svtweb.org/sites/default/files/2023-06/Billerica_RalphHill.pdf. All of the following numbers are located in this brochure.
Find the phone number of the Billerica Recreation Department. Put the last three digits here _______.
Find the phone number of the Sudbury Valley Trustees. Take the last four digits; divide them by 100, round down to a whole number, then multiply by two. Put that result here _______.
