I thought you were pulling our leg in regard to 20 antelope pts but noticed on the CDOW page there is 1 poor soul w/that many pts! If your buddy has waited 20 years he may want to wait several more years for antelope numbers and quality to build? Antelope numbers in the NW corner of the state that historically produced a few B&C bucks are almost non-existent other than a 10 mile radius around the city limits of Craig. That area has been pounded by deep snows and before that there was several super bad droughty years.
Colo historically is a pretty pathetic state in regard to B&C entries. There are a few scattered units around the state where a few book bucks are harvested but not many. I believe Eastman shot one that went B&C in the southern part of Colo last year and that may be a good place to research?
