It seems weird to me for a guy to be carrying that much cash what with cashier's checks and wire transfers being what they are, but I understand that Pakistan doesn't have all of the bank branches and technology that we have here in the states

That is the point, its weird to you.
I have carried 60k in cash and millions in checks when I worked for a major corporation.
In this day and age, you're nuts to carry that kind of cash with you unless you're headed directly for the bank to make a deposit.
Aside from the prospects of being ripped off, the cops can take away that money from you without charging you and you have to litigate to get it back (the burden of proof is on you). Under the current asset forfeiture laws, the cops only have to "suspect" you of using the cash for a drug transaction and their "logic" will be that you wouldn't be carrying that amount of money for anything legitimate, so it must be for a drug-related transaction. If you're doing this on behalf of an employer, your boss is going to be less than happy with you.
