Have you ever thought about adding an acoustic guitar to your property to make it more cozy and fun?
In the case of apartments, this is less feasible because of loud noises, but in houses with large patios with a fire pit it might be a good idea. Many travelers would like to relax to the sound of an acoustic guitar and distract themselves by playing some tunes, not to mention you'd be giving the house an artistic look.
What else would you put there aside from it?
