Last week I found someone with a hand saw on Severed, chopping off branches he thought gave riders a better view ahead. While I applaud the initiative, concerns on trails with a dedicated builder (adopted or permitted) should be left to the builder. Contact the NSMBA or post it on the trail conditions thread, don't start redesigning the trail. I've been trying to keep the trail a little closed in to reduce bike speed, but now it's a motorway the speed is going up. Severed started life as a hiking trail and still sees more foot traffic than bikes. I'm just thankful they haven't taken a chainsaw out as on Crippler. Please respect the trail builders.
Sustainable will be around forever.
