Not going up singletrack at a 15% grade. Coming down, yes, but it's not so bad. It's pretty steep here in Southern California; I don't really ride anything that approaches flat around here except a small part (~4 miles) of my 20 mile road commute.
I do change my mountain bike gearing to 34:15 for 'cross racing.
