Regulars that ride at Sierra Summit don't ride out the flat spots, they head down the right runs. The runs are easy to find on the trail map. The three flat areas can be challenging in the spring, I agree. Even so, I'd rather walk out a ten minute hike at Sierra Summit, if I went the wrong way, then wait in a 15-20 minute lift line at Heavenly $$$$, Sierra at Tahoe $$, Mammoth $$$$, Breckenridge $$$$ and Dodge Ridge $$ on any given weekend. Been there, done that over the years.
