Just got word of an intriguing Tweetup for photographers via @The BigKlosowski. It's taking place August 31 on the top, unfinished floor of the in-progress Four Seasons Tower downtown. From up there, you'll get some unparalleled views of the city, the mountains and, if you're prone to vertigo, perhaps your stomach contents hurtling into space. There's no charge to be part of this historic tweeting (sorry, I could not resist), but remember, it's aimed at photographers, so at least borrow your roommate's battered SLR if you're going to go. Admission is limited to twenty five, so you'd better act quickly. RSVP at the EventBright page and send us links to your photos.
