I've received quite a few queries in just the week that I've been here, asking what my people and I can use. Camp Leatherneck does have a USO, and it's well stocked with many essential items.
What we got:
What we don't got:
Sugar-free cough drops (Not sold in the MCX, either)
Aspirin (These three are in the MCX, but only in single serving packets)
Tylenol (generic is fine)
Benadryl (generic is fine)
We do get in jerky sometimes, but it's rare, and appreciated. As always, feel free to send John Ringo, Larry Correia, and David Weber books. ;-)
