Here's for the posterior leg....for the glute guys out there...

There are much smaller nerves that branch off of those pictured as well. I'll try to find a good image.
Actually, this one is really good:

This is about 1/3 of the way down the thigh and will show most of the major nerves the best, being at their thickest points in the leg.

Happy poking.
