Fifth Street Rock Monster
The Technical Tango
Sunday, April 11, 2027
Forever Farm | Mertztown, PA
Welcome to the Fifth Street Rock Monster. We’re throwing a spring awakening at Forever Farm. A slice of private singletrack heaven normally guarded by gates and "No Trespassing" signs. This is the only weekend of the year you’re allowed on these trails without a court date.
It’s technical, it’s rugged, and nature will likely try to trip you. But hey, we’ll have a beer waiting at the end.
The Details (Pay Attention)
The Vibe: High-energy singletrack, questionable jokes, fly tunes, and fresh food.
The Course: Continuous loops. Simple navigation. Same suffering.
