I've looked all over and cannot find it. Anyone tell me how to find it ... landmarks?

Where a character enters Salida Del Sol Norte, it is in a room almost directly above the stairway down, on the second level through a hole in the wall, loot the desks and a Deans Stash too.

It's a little tricky to get to. Tacking onto Bradley's post, it'll be in a hole in the wall when you look up so you'll be shingle walking.

Or, as I've so kindly looked it up for you. Here's a video walkthrough.

Thanks Bradleyh. I looked around there but I must have missed it. I'll try again with your directions, when I play Dead Money in a little while.

Thanks for the info and also the link, Colonel Martyr. I'll check out the link only if I really get stuck.

When you get to the room make sure to check the desks stacked against the wall as well as getting the Dean's Secret Stash and the Snow Globe. Then tend to have a lot of chips and other nice loot for whatever reason.

Will do, Jojobobo. Thanks!

Pro-Tip, unless you're just really bad at the game, odds are, once you're inside the casino, you'll have very very few needs for the Madre chips, so go the the casino section, break the bank and cash out 90% of your chips into Pre-War money. If you've been hoarding chips, this can net you a good 5-10,000 Pre-War Money bills, which can net you a bunch of caps.

Just a friendly tip if you want weight free gold.
