Video Report: Summer in National Parks

Pauline Frommer visits CNN to answer viewers' questions about visiting National Parks this season. In this clip, she discusses:

• Ways to save money on park vacations
• The rich diversity of the parks
• The best parks to hit if you want to avoid the crowds (hint: they're in California, Colorado, Tennessee, and North Carolina)

Next week, Pauline will be dishing on the airlines: delays, cancellation, byzantine pricing structures, you name it. If you have a question for Pauline on airline travel, send it to pauline@cnn.com and she'll probably answer it on air.
