The day may get hot this particularly warm spring we're having, so meet 6:30 a.m. Pringles Liquor parking lot (NW corner Drake and Taft Hill) for a 6:40 departure. Much of the hike is in pine tree shade. Please let me know if you can drive a carpool. For Lory State Park, the Colorado State Parks Pass is required, or pay the approx $10 day entrance fee.
