Block Party organizers Dave Meinert and Jason Lajeunesse have been making the rounds to Capitol Hill businesses the last couple days gathering signatures with which to petition the city to allow Capitol Hill Block Party to run a third day, on Sunday July, 25th. Meinert says the Sunday date would largely be to accommodate the schedule requests of one rumored to-be-playing band, and that Blue Scholars would also likely play the Sunday date if the city's overseer of special events permitting, Virginia Swanson, approves their request.
Update: Meinert adds:
We need to get as many residents on Capitol Hill to write in support of the 3rd day as possible. People can email us at firstname.lastname@example.org or fax to 206-374-2700. And important to also email the city at Virginia Swanson (Virginia.Swanson@Seattle.Gov).
Also keep in mind that a 3rd day will make a lot of local employees a lot of money and raise money for KEXP and The Vera Project, the two charities the event benefits.
And, as noted here: we know, it's a crime to charge money for an outdoor concert.
