It's National Parks Week  and through Sunday, April 29, you can get into any national park for free.
This weekend might be a good time to take a trip to the Indiana Dunes National Lakeshore  near Chesterton, or the Lincoln Home National Historic Site  in Springfield, Ill., or the George Rogers Clark National Historical Park  in Vincennes, Ind.
If you have a tablet or smart phone, this is also the week to check your app store for the free national park apps provided by Maine-based Chimani.com. 
There is an app which lists basic information about all of the national parks, and detailed apps for specific parks with more information including trails, emergency info, photos, a trip journal and more.
These apps are normally available for $4.99-$6.99, but until Sunday, or until the site registers 1 million downloads, they are free.
Here's hoping you find yourself in a park sometime soon!
