When we picked the venue we were so excited that we picked father day and didn't even realize it (oopsss)
i liked another day first but they were already taken so I though 06/17/18 was also a cool date. later on we realized it was fathers day... its a 5pm ceremony on a Sunday so we figured it wouldn't be too bad and my dad feels like on fathers day hes getting a cool present: a son 
we were thinking or maybe giving gifts or something for the dads who would be there but we didn't want something too expensive .. and we didn't know if that would be tacky to do?
