Lenawee Christian Center has a Course located on their property. Although it is probably required that you technically ask them for permission to play their course, they do not have a problem with the public playing on the course, as long as it is respected.
The course is a short course - there is only ONE hole over 300 feet (hole 7). It is an excellent beginner course, helping the new disc golfer concentrate on gaining distance and accuracy while not penalizing them harshly for not being "dead on" with their drives. For an experienced disc golfer, its probably not worth more than a 20 minute drive to get to the course - but, if you live nearby, its an invaluable practice course for practicing your 150 foot upshots and putting.
The baskets, unfortunately, are plastic-chain baskets. A lot of discs will fly through them if they have a lot of speed. Just feel confident knowing that if you were at any OTHER course, it would have went in! :)
Update! as of 2007, 4 of the 9 baskets are now metal chains. The other 5 are still plastic!
