Denver does have it's flaws (lack of facilities, lack of parking, distance to staging, altitude, etc) but if you haven't been there before you are really missing out. It's really a beautiful place to race and the Bandimere family is top notch. It's the only place I have been to and had the owner come up to me, shake my hand and personally thank me for attending.
Most of the complaints are due to the fact its built on a mountain, they can't just expand parking or run waterline like any other facility.
When you're there make sure to head behind the mountain into Morrison and grab a Jauns Gold Margarita and "The burrito that ate Jarez" It's tradition for us
