A few days at a lodge in the town of El Portal, with daily excursions into the park and
over Tioga Pass to Mono Lake. (Disappointing note: due to lack of rainfall the lake level
is no longer rising; in fact, it is still well below the minimum level ordered by a court.
NOTE: USG has a deal for you! If you're over 60, a lifetime pass to all the national parks is only $10.
Compare that to a week's pass for each park at $20.
