Good to hear Rande. I always point folks here for decent trail info. It is a little dated now as some trails are a bit rougher ride.
The ride from 550 to Engineer is pretty bumpy on the initial climb compared to 10 years ago. Ophir is one of my favorite scenic drives with a little bit of shelf road. I did Brown Mtn for the first time last year and really enjoyed a different view of Red Mtn. Last Dollar is one of the lower roads and has lots of forested trail. Avoid this one if it has been raining.
I would also suggest Sunnyside Mine.
