you can get your a dad a new acoustic guitar so he'll be more excited and looking forward to play country music again. Just by hearing music can already rejuvenate our soul and even heal our hearts, so your dad would be more than happy to have a new acoustic guitar and play Country music again.
I'd like to get my dad something a little more personal level.. his been dealing with a lot of stress because my mom is sick and so i'd like to really cheer him up.
you can give out custom print car sticker that is printed with number one dad. employees who are fathers would appreciate it especially if you have a ceremony or special program on putting the stickers on their cars.
