Old Red Lace, Sierra Santa Lucia would be my guess.

Thanks, guys. I have googled TeePee Canyon now and I have found a page from Red Rose Rock Shop that shows the same type of material, same matrix, everything. I never would have ID'd this on my own so I am very grateful.

Hmm, I'm tending to go with JR on this one and say red lace but would rather see a cut face. Tee Pee's tend to have a grayish to buff brown smoothly patterned matrix to a fairly smooth nodule. The agate part sure screams Tee Pee but you really can't see much of the pattern in the pics. To me the matrix does not look Tee Pee. From what I can see of it, it looks much more like what I'd expect from Mexican lace. Might go with the others if I saw the cut face though *L*.....Mel

Look again at the second photo and you can see the smooth rind of the original nodule between two broken faces. Lace agate (at least the popular red crazy lace from Mexico) is mined from a solid hard rock layer without a nodule rind.
The stone appears to have been laying outside for a while and has grown some lichens/moss, but you can see the buff colored rind between those two breaks.
The agate color is also classic teepee, right down to the pink and yellow inside the orange bands. It actually looks like a decent piece and there's a reasonable chance that the pattern will improve inside the nodule. Might cut a killer specimen!

Good catch! It has been laying around outside for at least 20 years! Maybe I should dip it in chlorine to remove the stubborn algae or moss...

The reds in that are a gloriously rich color. I'd bet on the lichen/algae growth as well.
You might want to try what's suggested for shells if it's algae removal; I keep reading to soak them for 24 hours in a 50/50 bleach/water solution, preferably in the sun, then rinse very well and scrub with soap/water/brush to clean the muck out of the cracks. It works pretty well.
I've done this with the beach stones I bring back, even those that seem clean, to help ensure the chance of any lingering bacteria on them is minimized. One word of caution, though: that's a very, very strong bleach solution and while it seemingly makes sense for shells, which had living critters in them at some point, it can likely be diluted a more for stone. Definitely use gloves if you do the full strength version above; bleach burns creep up very nastily.

Done! What a difference some chlorine and a few hours can do. Thanks again to all who helped me with this specimen. A view of the white/light rind: A view of the whole specimen. May trim it a bit more later, haven't decided yet:

Hey, that's a nice one there!!
I cut a few hundred pounds of this stuff on shares for a guy once 10 or 15 years ago, but it was all pretty badly fractured. Nothing as pretty as the piece you just showed!! Nice agate...
