Do you ever feel that when you're online you're neither here nor there? If so, NYCWireless and the Downtown Alliance want you to explore the possibilities that open wireless (Wi-Fi) networks may provide for connecting virtual and physical space. They are co-sponsoring Wireless Park Lab Days, two days of events designed to expand knowledge of Wi-Fi networks and create new ways to use them. Aside from the new user area to encourage interested newbies, there will be a wireless art exhibition featuring creative and critical uses of wireless technology and a chance to play the scavenger hunt-like Noderunner. Events will be held at City Hall Park in Lower Manhattan on September 19-20, from Noon to 4PM EST. Even if you're not feeling very sociable, you can always do some virtual people watching. - Ryan Griffis
