amex checks have to be declared. i would also think any kind of guaranteed drafts would have to be reported. i carried large guaranteed drafts made out to various entities and drawn on the foreign bank of their choice.

i have some high limit atm cards. individual and daily pulls are limited to either 1500, 0r 2500 per card and account, i forgot which. i have 2 etrade cards, and can max each at the same time. i though about putting more money into more of my etrade accounts, or checking the limits on atm cards at other brokerages in which i have accounts if i get back into a cash necessary business.
