I just went through my bank statements year to date and realized I've yet to make a single ATM withdraw so far this year. I dont have any cash transactions.
I do have an upcoming road trip where I'll be driving through W Virginia....and they still have cash toll booths SO I'll need some there....but otherwise the only place I think I still use cash is in Vegas.
I have to believe that is going to be on its way out in the near future. It will be interesting to see how money is exchanged 10 years from now.
