If you'll be in the Concord area, then try turkey pond, have fished it in tournaments before. Not a great boat ramp, but fishing is good here.
That's exactly where I went, actually. Only fished for about 3 1/2 hours, but it was worth it. Got about six bass, but one was a 4.6 and another was a 5.7. =)
I'll post a video soon.
