Are you stock or lifted?
There are tons of trails within an hour of Auburn. Rubicon, Fordyce, Deer Valley, Signal Peak, Strawberry Pass, etc. There is also a ton of NF land around that you can go explore. One of my favorite spots is in Foresthill. About 2 miles out of downtown Foresthill take a left on Finning Mill road and then take that down a couple miles. After about 2-3 miles it turns from private to NF land. There are tons of trails and you can camp, shoot, quad, dirtbike, whatever.
Here are a couple sites with trail reviews:
