Hunters share a mix of experiences about Unit 64 in Colorado, with several noting the challenging terrain and recommending good physical preparation for steep and rugged areas. The unit's elk population appears healthy, but hunters emphasize the necessity of understanding elk behavior during different times of the season, particularly during the rut. Draw odds are competitive, so it's beneficial to apply with a solid plan and possibly consider less pressured pockets in the unit. Patience and scouting are consistently mentioned as key elements for success in this area.
