Suprise Birthday Party?? Ideas Please..

Hey everyone.. I am wanting to have a surprise birthday party for my soon to be 21 year old boyfriend.. We`ve been together for 3 years and I would like to make this special for him. I am 20, so I`m completely able to do this, I just need some ideas like where to have it. I live in Georgia and anywhere in Atlanta would be convenient. If you could e-mail me with ideas I would gladly appreciate it :) Please just make the Subject "Important Ideas" so I`ll be sure to look at it. Thank you!
