Dave Peck from WhereBeUs will be presenting on Mapkit and Core Location. With the release of iOS5, there are no more NDA restrictions on new Location features such as forward-geocoding.
The meeting starts at 7 PM at Thinkspace in conference room 101. Thinkspace is in downtown Redmond very close to the Redmond transit center (ST Express 545 from Seattle). There is also plenty of free parking.
