If you have nothing else to do today, you might want to wander over to Ross Elementary School, on R Street between 17th and New Hampshire NW, for their Spring Festival Fundraiser (held between 12 and 5 p.m. today). The school is trying to raise money to support things that DCPS doesn't find important enough to require, like PE and the arts (Ross students take part in the Fillmore Arts Center, and this year the PTA provided funding for that program). There will be a silent auction with some incredible items and various activities for young and old alike. Additionally, the Fillmore jazz ensemble will be playing.
I believe tickets are $10, and all money goes to the PTA and school funding.
