I do alot of staring at folks like I know they are up to no good. I then usually bark "move along" or the how long have you had...I like to stand guard at door ways, point at people etc. I always wave at the kids, babies included and usually holster my weapon when interacting with children.
folks also like to see troopers doing things that normal people do because it's comical. One time I push my middle son around in his stroller, alot of folks took photos.
