will they all be there at the same time? have you hired security and parking attendants? got enough talent to field 2 teams for a football game in the yard? will alcohol be involved at all? good luck!
parking is not a problem here. I can get a dozen cars in my driveway and the rest can park on the street. Getting them through the gate will be a bigger problem. Some of my family will have to call in as I refuse to give the gate code to all of them.
Alcohol will be a plenty, however there will be no less than 4 alcoholics there and a couple of recovering drug addicts. I am not allowing any hard drugs, but I have set up a cool little smoking area under tree canopies in the corner of the lot. I am pre-rolling a cord of blunts as that is the only way I can handle the family festivities.
