I use mostly cash for day-to-day expenses. I often start out with about sixty bucks but the amount dwindles, so it is often less in walking-around money. I'm parsimonious with plastic, since those expenses can incur interest and fees, and I try to pay them off completely every month. In a larger city, I'd have to carry half again as much, and maybe half as much in a rural area. Plastic is easy, but if anything goes wrong with bill-paying, the big corporation has their hand in your pocket big time. When I pull out plastic, a red light goes off. My habits are so 1950's, I seldom use an ATM. It used to be required to get travel money at work, but I haven't used them regularly since. My brother-in-law calls them "money from the wall."
