Auburn would be fun. Here's an idea that will give you each want you like- if you don't mind splitting up for a bit:
Check out the link below. Park at the northern most point where the Forest Hill Divide Trail crosses forest hill road. Head counter-clockwise around the loop from there. When you get to the Forest Hill Connector trail, you take that south to Culvert to Confluence, and she keeps on the Forest Hill Loop, pedaling back up to the car.
Then she drives back down the road to meet you at the parking lot at the bottom when you enjoy a beer by the river. Best of both worlds--DH for you, climbing for her.
