The theme of the month is 'search'. I've been meaning to add keyword and time-based searches for a while now and now you have them. The 'advanced search' option lets you specify a whole range of options by which to search, including keywords and opening hours.

For convenience there are also a couple of shortcuts. To find out which locations are open right now you can go directly to http://grwifi.net/open/now and to find locations in a particular zip code you just go to http://grwifi.net/zip/xxxxx (ie. http://grwifi.net/zip/49503).

Enjoy! And don't forget to email wifi@grwifi.net if you have comments or suggestions.
