Murmur creek is easy when the snow melts and I've done it in my VW Beetle as well as by bike and pick up. A friend of mine lives on the east end of Deer Yard Lake so I take it often from the Caribou Trail. It can be pretty muddy as any of them are in the spring.
From Babenau's Corners it's well marked now with a road sign and some new gravel because last summer the DNR put in a new boat launch for Pike Lake from the south side.
Sold the MG today so the bike is soon.
