We Americans are just resistant to change. IF it happens, it'll take some getting used to, but we WILL get used to it eventually.
If change was like sex, you'd be all over it.. :24:
Seriously I have Americans that come up here and get use to the $1 and $2 dollar coins..
We also take American money almost anywhere.. Most US Border towns will take Canadian Money but go 35 miles South and that ends..
