And then I think, use the search feature on FB you dummy. And I found what Matt wrote in August:
PSA- We have 4 weeks until the annual MIBC Drummond Island trail ride September 12-13th. We have plenty of spots for Friday and Saturday still available. You can see both Friday and Saturday registrations on the event page, I posted Fridays registration page below for attention. Almost any stock Bronco is capable of making the trip. My caution is running boards, they can get snagged on rocks occasionally. In most cases they come off in about 20 minutes with an impact driver. The event goes something like this- Friday morning drovers meeting at 10AM at Pins (DI Resort). We run the Turtle Ridge Off Road park from 10:30 to 4PM, we let people split off, check in, run to Fossil Ledges, Dinner etc. For those interested, we do a night ride which is one of two “out and back” loops. Everyone wants to use their off road and rock lights right 
? Saturday morning is a 9AM drivers meeting (at Pins) and a trial run to Marblehead. Lunch on the trail, then loop back to the resort. Saturday night we try and do something together (bonfire?), Sunday drive home. If you have never been to DI, this trip looks like a great opportunity! Here is the Friday ride registration
