It's not all about altitude Huey, it's all about technique. A powered out G2 at 2500 feet can teach you as much about technique as a powered out 407 at 16,000!
Most of the basic Ops in OKanagans (not CHL's!) mountain course are (were)taught on Bud's Knob, a non-descript piece of rock about 4500 feet. That rock has caused more grief and more suffering to the Mountain student in the last 55 years than any other rock in the country.
Success is not measured in just landing there, it's measured in how many percent Q you used, and if you can match the master...at 76% or if you needed 79%.....
But Tillotson and Wayne Grover etal wrote a great course, and the present group have carried the quality forward.
I agree with T-Rex, greatest school, shame about the company 😀
