These should be available to view most of Thursday as they build them. All day Friday and into the evening as well. Most spectacular in the evening when when all the candles are lit. Years past the High School has done this and I think a Secondaria. This year it looks like CECYTEJ (technical school in Jaluco) has the honors.
For people that want to see the real thing in the area Panteon ... most decorations will be placed November 2nd. The Panteon is out Highway 80 and you are welcome to visit. At night not advised.
