In our quest to see as many archaeological sites as possible, we finally went to Ixtepete this weekend. It's just off the periferico on Mariano Otero so it's not very far away and it has a decent little pyramid base. It was worth going to since we're going to everything we can.
However. I can't recommend that it needs to be visited by anyone unless you really like pyramids or if you're looking for some kind of real life RPG (I have no idea what they're called, but I hope you get the idea). There were all kinds of people there in various outfits with great homemade weapons running around. It's a great place for that.
