I did my first dual sport ride on Sunday with a group of 28 others.. most of which were first-timers also. I must say that with the pressure in the tires @ 25, I felt very comfortable in the dirt on the big pig and I did quite well. I think my mountain biking experience helped alot.
Lots of water crossings, a few hill climbs and some mud made for a very fun adventure! I think i'm hooked!
Here's link to some videos I took at one of the many water crossings.
