This was our first official trail building day at Merus Adventure Park. We worked on the BERGflow trail and had a real adventurous day. It started with thick fog and turned into a severe thunderstorm by the end of the day. There was actually an F3 tornado within 7 miles from where we were by 4 pm that afternoon. We managed to build about 1.5 miles of hand built offroading trail before calling it a day and it's really a phenomenal section of the BERGflow trail.
