According to GJSentinel.com the Sheriff's Department had to "aid an injured mountain biker on Mary's Loop" on Tuesday. Most of Mary's is tame and a lot of fun, but there are some tricky spots where, if you're like me, one false move can leave you bloody or worse, seriously injured!
Be super careful around the first portage, with the "caution" sign. Even when walking your bike through there it's slippery and could lead to a nasty fall.
Of course, be careful on the 1/4 mile or so stretch of exposed trail leading west to Pizza Point!
Always always let someone know where you'll be and carry your cell phone. You can get reception almost anywhere out there and it could be the difference, literally, between life and death one day.
Have fun and stay safe and keep your fingers crossed for good riding weather soon!
