Follow me to Japan

So, I've finally got enough money to open a bank account (about $300). My dad sent me $200 to go towards my trip and $100 for my birthday. My Grandpa also sent me $100 for my birthday. Because I am a teen and I need to pay for things that are almost directly related to school I'm half-ing that so that I have spending money.
I'm including them in my offline donations on GoFundMe in hopes I will get on the main pages.
So now I am opening a bank account, but my mom is always really irritated with Bank of America (which is her bank) so I'm a little iffy about using that bank. I've been looking up foreign exchange rates and stuff and since I don't want to have to deal with a new bank all on my own I think I'm just going to go with Bank of America. So yay.
