A non-lift serviced alpine ski trail on the east face of Mt. Greylock in western Massachusetts. Has hosted an annual downhill race for over 75 years. The 1.6 mile long trail has been used in the past by olympic skiers. Named after the Thunderbolt rollercoaster which was located in the former Revere Beach amusement park.
After humping Greylock and downing a sixer of PBRs, Josh slapped on his splitters and began to shushboom down the Thunderbolt until he wiped out and had a huge yardsale.
