Since I've been longboarding, I've found out that the best hills in Fort Collins are in the hills around the reservoir. They're really not hard to find up there. The only thing I have to say about them is be careful. It's mostly rough pavement and long hills with sudden tight turns that seem to almost corkscrew down the hill. I've gotten the fastest I've ever been up there and it's quite buck!
         As far as my favorite hill in town; that goes to a hill that I believe is pretty underground, along the grounds of longboarding. At the Hummel Lane and Front Nine Drive crossing, off of South Lemay Avenue, is  where you'll find two buck hills. They're short but they make up for it in steepness.
        Hummel Lane is more laid back than Front Nine. It starts off at a decent slope with a beautiful backdrop of the front range in your view. It turns left as it flattens out but you should be carrying enough speed to get that adrenaline rush. Then the road comes to a "T" at the bottom perpendicular to Front Nine. I try to make wide "S's" towards the bottom and I take the sharp right turn onto Front Nine by carving to the right side of Hummel while turning onto Front Nine which ends with a cul-de-sac/court.
       Front Nine Drive is a much steeper hill. It's more of a thrill ride than a hill. Front Nine does have a slight curve to the right but it feels more like straight down. This hill is a beast of a neighborhood hill. Just be careful at the bottom. There tends to be debris in vital points of the cul-de-sac if you prefer curving around the perimeter of the the cul-de-sac like I do. I've lost a chunk of my right knee to the coping of the street drain at the bottom after going down Front Nine. I also got a buckin' concussion.
Should have been wearing a helmet.
