Help Me Convince My Mom

I have started planning my sweet sixteen party, its not for a few more months but i need that time to convince my mom to go with the idea. I realy want to have a bbq set up later int he day, but hen have a big camp out in our back pasture. The only problem is convincing my mom to let guys stay. I plan on having every body stay in tents with there own sex, but my mom is still not sure, i just need some advice from all of you moms out there, on how to convince my mom it will be okay, thank you much, ~Tara~
