It has been a few years since I've ridden Hole In The Ground and I see on Trailforks there is this "Culvert Connector" trail to avoid the bunny hill fireroad between soda springs and boreal parking lot.... is this a thing? I checked Strava Heatmap and it looks like hardly anyone uses it. Anyone tried it?
