Fun Ideas for Father's Day?

Well... I'm doing photos of my 2 year old DD for my dad, my FIL, and my hubby.

Hubby is a cowboy. ;) So I'm going to take a picture of our DD in his hat, his boots, and her pink tutu. (she actually dressed herself up like that one day, and it was sooo adorable)

My dad is a welder, so I'm going to get a picture of her in her pink coveralls, and a welding helmet.

My FIL is in construction, so she's going to be wearing a hard hat and safety vest.

You could buy a few nerf guns, some targets, and have a nerf war with him and the kids.

Take them paintballing (if your sons are too young for that, paint gunning or paint ballooning...)

We're going camping for Father's Day weekend. :)

I think you are on track when you say you might take him shooting.
Doing something HE would LIKE is the best thing. Isnt that what we CRAVE for mother's day?
If we do something fabulous (that they would like) for Fathers Day, it sort of help insures that Mom's Day will be more "thought"ful too.
It's about what THEY want not about what we THINK they want.

Camping, fishing, golf outing. I know my guy would like breakfast with the fam then a day ALL to himself as a "reward" for father's day!
