Father's Day is Sunday, the 19th this year so with a week left to spare you can either run out, grab a card and a generic gift and be done with it OR you can check out the ideas below that I'm sure any dad will appreciate.
If you have a dad that loves the outdoors, consider going on a day long fishing trip. You can look for kayak/canoe rentals at state parks near you and spend the day on the water. It's great bonding time.
If you have a dad that loves sports, consider going to see a local team play. Minor league baseball is ALWAYS a fun time.
Who can go wrong with food? And if your dad is like mine and isn't a huge fan of going out - COOK!!! No dad can resist a grilled steak with some potatoes and veggies!
If your dad loves the same type of films as you - head to the movies for a date with your dad!
See? In 4 quick examples I just gave you some great ideas!!!
