The only useful information I could extract was that all accounts are closely monitored once they hit $20K in cummulative usage, since they need to fill out forms under Federal anti-money laundering laws at that point.</font>
If that's what they told you, they were blowing smoke. The forms that must be filled out that they are referring to are the Currency Transaction Reports (CTRs). A CTR must be filled out for any cash transaction that exceeds $10k. Banks can consider a series of transactions as one (and fill out a CTR) if they think you are performing multiple transactions in an attempt to stay below $10k per transaction (meaning I go to the bank twice in one day, each time withdrawing $7,500. In this case, the bank is supposed to consider these two withdrawals as one transaction).
The fact that you used a credit card to purchase traveler's checks (I think that's what c2it was used for, right?) over a long period of time does not appear to count as one transaction, therefore the bank does not have to fill out a CTR.
