If you wanna see a big parade this weekend, head over to Howard University for the Homecoming parade. If you plan to drive somewhere, however, I would steer clear of the area.
The parade is pretty cool -- very big with lots of music, food and vendors. There's also a ton of other events -- the Steve Harvey Morning Show, concerts, comedy, etc. Check the website for the whole rundown.
Going on today is the Howard Yardfest, a concert with Fabolous, The Clipse, and Cameo -- yeah, the old school band. It's from 1 pm to 7 pm.
The parade runs from 10 am to noon on Saturday and the route goes down Georgia Ave, onto Florida, then up into campus. Click the map at right or click here for a bigger version.
