15 of 59 - The National Park checklist

With the addition of Pinnacles National Park in 2013, there are currently 59 National Parks in the United States; by my count I've visited at least 15* of them:

• Acadia
• Badlands
• Glacier
• Grand Canyon
• Grand Teton
• Haleakalā
• Hawaii Volcanos
• Kings Canyon
• Lassen Volcanic
• Mesa Verde
• Redwood
• Sequoia
• Shenandoah
• Yellowstone
• Yosemite

I really need to get out more...I'm barely at 25%! An Alaska trip would help knock a bunch of these out.

*It's also possible that as a kid I visited Crater Lake, Olympic, and Rocky Mountain. I don't specifically remember, but these are likely suspects for family roadtrip vacations.
