Those who visit Metro Bistro beginning this afternoon will notice a”free wifi access” sign in the window. The popular downtown bar/hang out spot has become #333 on Bhamwifi.com’s ever-growing list of free wireless access points in the metro Birmingham area. The list began in late 2004 with less than 50 locations documented ; it now contains 97 listings for the City of Birmingham alone. The website is a partnership between Internet Professionals Society of Alabama (IPSA)and TechBirmingham.
