The suburbs pose an interesting conundrum since what there is tends to be spread out.
Privacy Fence: cat leaps, tic tacs
Front Stoop: train drops
Lawn: rolls, anything you want a softer landing than concrete for
Driveway: use the lines to practice precisions
Balcony/Railings: vaults galore
Picnic Table: vaults, palmspins, drop training
Trees: underbars, pullups, wallups, tic-tacs
Benches: vaults, precision walking, cat walking, precision from bench to bench if available
Don't forget you can condition anywhere too. Be creative with what you have and you'll be fine.
