Ok so if you go around to the cities and stuff you know, places like downtown. Here is where to tap

Brockwillow - birds, cars, trees, newspaper box, trash cams
Apartment - if you have a pet, the mouse at the end of the house, the lamp over your couch
Armies - mug, trash can
Cromtown - same as Brock willow
Bar - the pool table money slot

That is just some keep going around to different stores and places tap signs, security cameras, pictures, trash cans, bottles, drinks, you name it.
