The best way to beat the crowds in Yosemite this weekend is to go somewhere else. I recommend wine tasting in the Salinas Valley. Just remember - taste the wine, don't drink it. Save that for home.

Personally I'm a fan of wine tasting in Sonoma County. But beware of the cyclists. The person you piss off might just be me.

Mostly good information in the article, except for one blurb: "But, notes guidebook author and photographer James Kaiser, Yosemite is located in a remote, high altitude area free of light and air pollution..."

Ah, no. Sadly, Yosemite does suffer, at times significantly, from air pollution, and even to some degree, even light pollution, though not as much as in more urban areas.

The National Park Service does have a philosophy of reduced light pollution. If you try walking any lit parking lot in Yosemite NP at night, there are few lights and the ones that are there are intentionally set for low output. It gets to the point where it helps to carry a flashlight even to just get from your car to your room.

I don't know if Yosemite goes as far as some places. Bryce Canyon NP is well known for its nighttime guided walks, where one is encouraged to just let the eyes adjust to the lack of light. I recall some NPS nighttime programs recommend the use of red lights (I once bought a lens kit with a red filter for my Petzl headlamp) to get around. I don't know what the red light is supposed to do, but I'm guessing it has something to do with light pollution.

It's all due to "The Turlock Effect"

Oh God, not again. I think the Turlock Effect is a form (forum) of disease.

Are you saying we need to flush the Turlock?

No way. It's part of who we are.

Every time I read the subject line my brain wants to add "with a stick."

Probably because around hour two sitting in traffic trying to get out of the valley, I actually consider that a viable option.
