Lost and Found

I just bought a sweatshirt last week, and I can't find it. It's a black and red Nike and the last place I remember having it is this Saturday afternoon at ECAV. I checked the field today but to no luck. Anyone know a lost and found, where I should start looking, or if it's a lost cause?

Edit: Thank you everyone for being super helpful. I emailed the intramural guys and the random athletics email I found on the rpi website and explained the situation and by some ridiculous chance the guy who answered back found it!
