Then the 404 Day Block Party takes over Underground Atlanta from noon to 5 p.m. with live music, food trucks, and local vendors.

Friday night offers a preview with the "From 404 with LOVE" rooftop event at The Interlock, featuring a live band and awards for notable Atlantans. If you want to support scholarships, The 404 Fund Gala happens Thursday at Monday Night Brewing's Garage location with $150 tickets.
