The cache of 540 rifles, 165 grenades, 500,000 rounds of ammunition and 14 sticks of TNT were seized at a house in Reynosa...Damned American gun shows.
That's where I get all my grenades and TNT sticks. From the table right next to the "Body-Piercing Done Here" AR-15 T-shirts, you know, the one that also sells the pricey elk jerky and Saddam playing cards.
You can see video here, and pictures here.
