The new site will have several new features. Specific changes in content are being considered. There will be a happy hour listing at some point, though not necessarily at the debut.
The best happy hour source I've found in Vegas is managed by the Las Vegas Review Journal. There's also an app to access the data on smartphones. I think it'd take a LOT of work to do a better job.
Better yet will there be a new site? Or will another february passes by again. The latter seems more likely. Well by now most have gotten use to the dial up type of speed.
