My boyfriend is turning the big 3-0 in September. His parents, sisters and I are planning to throw him a surprise party (although he already figures something is up and is trying to avoid it at all costs even though he loves the attention

). Just wondering of some fun ideas we can incorporate into the party on that day for him. So far the tentative plan is that it is going to be in their backyard, they are going to put up a big tent and have it catered.
