About this event
Come enjoy summer in Seattle and celebrate OpenStreetMap's 22nd birthday at Green Lake Park! (We're also commemorating 10 years since we hosted the State of the Map US Conference!) We'll be at the north end of the lake, just west of the wading pool. As always, newcomers are welcome as well as long-time mappers, to swap stories and ask questions. We will have a small grill and some grillables (e.g. hot dogs and buns). Please bring a chair and something to share!
