What part of Mexico are you in, Russ...
Chihuahua (4 hours south of Texas, halfway between the oceans). Its a great little city. I had in my head a picture of how people describe Mexico City (which I also have not been to) and its nothing like that at all. Its relatively affluent, clean industrial, and just plain beautiful. It'd be a nice place to live for a few years.

Mountain...? Good grief, man... the town that I live in is built on a hill 3 times that size.

BTW, what was the height of the mountain? It doesn't look like much more than a big hill in the picture, but I have no idea how far you're standing from the base of it.
Attached is a pic taken from my hotel room. My guess is its about 1500 feet vertically. Hey - I'm from Pennsylvania, anything over 500 feet is a mountain. It took about 1:15 to get to the top.
Also, by popular demand, an unrelated photo of me with no sunglasses. Its the only one I have on my laptop. And if you guys beg enough (or complain too much??), I'll post the pic of me with no shirt on

Now - let me tell you guys about my day. I'm a week into this trip and today I was really hoping to get started on what I'm here to do. My purpose here is simply to balance the airflow in the HVAC (heating, ventilation, and air conditioning) system. It should take about a week. All it takes is measuring air flowing from each diffuser (vent) and adjusting it via a damper (valve in a duct). Computer controls on the air handler (big fan) make sure the total airflow of the system is constant, so I only need to adjust each damper once. Simple.
The basic problem is that the constuction isn't finished, so none of the computer control is in place. So while we're adjusting the airflow at each diffuser, the flow properties of the entire system change and we have to manually adjust the whole system via some large system control dampers. And its taken a week to even get to the point where we could do that. We've had a host of small-medium problems.
Today's problem was that we finally thought we were ready to balance the system and manually opened the four large system control dampers. The actuators (motorized controllers) were in various states of existence (there, not there, partially installed and hanging unsupported, etc.), but there isn't any computer to control them anyway, so we manually opened them, which wasn't all that easy since they weren't finished being installed. It pretty much took all morning (there were some other minor issues to deal with too).
Upon returning from lunch, we slowly ramped-up the speed of the two air handlers feeding this system. My boss would say later that doing it slowly was a general precaution and he didn't have any real worries about it. Well, as we ramped up the speed, the ductwork made more noises than it should and eventually, we heard some fairly loud popping noises - the sound of the ductwork bursting at the seams, possibly one of the dampers that didn't have an actuator slamming shut, possibly damaging it. As it turns out, while we were at lunch, someone completed the installation of 3 of the 4 damper actuators and in so doing, closed the dampers. The fans built up the pressure in the ductwork, and the ductwork burst.
Had we just switched on the fans at full speed (two 15 horsepower and two 50 horsepower fans), like we had every reason to believe we could, they may well have blown apart the ductwork so violently that sections of it would have fallen from the ceiling. As it was, my boss had to climb inside a duct to inspect a damper that we thought may have been damaged.
On Friday, we laid out a schedule that had us starting on Sunday. Now, two work-days into that schedule and we are precisely two days behind. Oh, what surprises await us tomorrow...
