This is a nice observing site not quite as far as the Keota site (but not quite as dark either). It is on public land and there could be other non-astronomy folks there but it generally hasn't been a problem.
From the I-25 / Hwy 14 interchange in Fort Collins, head EAST on HWY 14 for 33 miles. Turn left/north on Weld County Road 69. Once you get to WCR 96 (the first 'major' crossroad as you head north on WCR 69), keep going another 3.6 miles north. Turn right on service road 609. If you reach Weld County Road 104, you’ve gone about ¼ mile too far north.
GPS coordinates are: 40 44.1058'N 104 24.4401W
