Inspiration Weekend 9 will happen in the DIY office from 10am until 5pm on Friday and Saturday at 1101 Broadway Street, Vancouver WA (the corner of 11th and Broadway) in downtown Vancouver.
Friday: You're going to want to park in a lot because there are very few long-term meters in the area. I recommend parking in the City Center lot (#18 on the map) at East 6th and Columbia Streets, just a few blocks south of the offie. Parking in that lot is relatively inexpensive and that lot accepts cards and coin for payment.
Saturday: On-street metered parking is free on Saturdays, and there is a ton of it around, so this is where I recommend you park on Saturday.
