It's definitely a sickness. Last year some friends came up for a weekend and we walked the field for a couple of hours and found 3 nice points. After they'd gone home, I found something that one of my kids dropped on the carpet and had to send it to them with the caption, "Found another one!"

It looks like a Wheeler to me, but Dalton probably works better for your area.
Are your kids old enough to try to describe your hobby to a teacher, or draw a family picture with you looking for rocks? That usually makes for an odd parent teacher conference.
