Q: Hikers can hike EVERY day. Only bikers on the weekends follow BIkes=EVEN; no bikes=ODD -Guest
A: From the JeffCo web site: On weekends, hike and horseback ride on odd-numbered dates; bike on even-numbered dates. http://jeffco.us/open-space/parks/centennial-cone-park/
Q: I rode Mayhem Gulch-Juniper-Travois trails yesterday, 2/28/16 and the sign right next to the trail head clearly stated that this even day was a "bikes only" day. Every hiker I saw on the trail had to completely disregard that sign and walk right past it as in, "Surely it doesn't apply to me, my girlfriend and my dogs!" Is this typical at Centennial Cone in the early months of the year? I saw at least a dozen hikers and no rangers giving out tickets! -kernreed
A: Tweet or text the rangers. They can and do give tickets to hikers and bikers who are there on the wrong day.
