We just got back from a week on Beaver Island. Beaver Island is located in Lake Michigan about 25 miles north of Charlevoix; a two hour trip by ferry.
We rented a cottage and biked, for the most part, where we wanted to go. We did rent a Geo Tracker for a day. It was $50 for 24 hours and you needed to replace the gas; gas on the island was $5.49 a gallon.
It was a wonderfully relaxing week.
Oh, and I finished reading "Wicked" too. Great book! Definitely not for children. Has a few slow spots, but overall a great read.
