Please Help Me Convince My Mom to Let Me Go To Summer Camp !!?

Okay; so I live in N.Y.C. [Manhattan/Brooklyn border] and I want to qo to this summer camp in Pennsylvania. It's for qymnastics and it is called Camp Woodward [you can look it up if want]. My mom said that she will think about it, but I don't want her to think about it and say "No!", I want her to think about it and say "Sure sweetie" or "Yes". By the way, if this helps you with your answer, I am 12 years old about to be 13, and my mom has let me do thinqs by myself before like qo to Texas by myself, which is way further than Pennsylvania. They have financial aid [my mom doesn't really need it with her salary, but it would help pay for the 8 wks that I want to stay there.] PLEASE! I need a really, really, REALLY convincinq and compellinq arquement! Thanks in advance.
