If you're in Michigan and you have a library card (and if you don't have a library card, what's wrong with you?), there's a great deal going from now to the end of September, combining two of my favorite things: books and nature. You can go to your local library and get a free pass for any state park (98 of them!), good for seven days (usually there's a $6 vehicle fee, unless you've got an annual pass). It's part of their new Park & Read program:
Many parks will also have a hammock available at no charge for Park & Read participants to borrow while on-site for the day so they can fully enjoy a great book in Michigan's great outdoors.
"The program was designed to give people a free trial visit to experience what a fantastic family and recreational resource their Michigan state parks and recreation areas can be," said Maia Stephens, recreational programmer for the DNR Parks and Recreation Division. "Besides, what's more relaxing than a day at the beach or under a shady tree with a good book?"
Here's a list of the Park & Read Parks with hammocks. Although the Saline District Library isn't on the list of participating libraries, since I found the link for the program on their website, I think they offer the passes, too. The Ann Arbor District Library is listed, along with Chelsea and Brighton libraries.
