Increased Airport Security and Cash

Anyone have any experiences with the new airport security and moving large sums of cash? I used to just pass cash thru with my carry on luggage but now I understand carry on luggage is searched.

Don't want cash seized on the assumption of drug money and have to go to the time and expense of proving it is legitimate. Now, I understand cash could be considered sign of terrorist activity.

I assume metal dectectors are now more sensitive. Will money belt with cash set them off or fail wand test? Hate to have to hassle with bank accounts and wire transfers.

Remember when America was free and you could travel freely?
