Doug Dickey. The original artificial surface was replaced with an updated version in 1980, and it remained until 1990, when newly hired coach Steve Spurrier insisted it be removed and replaced with natural grass to help prevent player injury. In June 2012, the playing surface was completely removed down to the substrate to install an improved drainage system and in-ground sensors to measure moisture levels and temperature. Since that work was completed, the turf on Florida Field has been a Bermuda grass hybrid developed by UF's Institute of Food and Agricultural Sciences to better resist drought, disease, and damage. The field is usually overseeded with rye grass late in the football season to compensate for wear and tear. Other home fields Florida has played the vast majority of their home contests at Florida Field since it opened in 1930. The most notable exception is the annual Florida-Georgia game, which has been held in Jacksonville since 1933 with the two teams alternating being the official home team. The only seasons since 1933 in which UF and UGA did not meet in Jacksonville were 1994 and 1995, when the old Gator Bowl was being rebuilt as the venue now known as TIAA Bank Field for the NFL's expansion Jacksonville Jaguars and the contest was held at Florida Field and Georgia's Sanford Stadium, respectively. In years past, Florida would occasionally schedule a home game in Jacksonville, Tampa, or (less frequently) Miami and Orlando. But besides the annual meeting with Georgia, the Gators have not played a regular season home contest anywhere besides Florida Field since September 1980, when they defeated the California Golden Bears in old Tampa Stadium. Not coincidentally, this game was played the season prior to Florida Field's south endzone expansion, which made it the largest football stadium in Florida. Home field advantage The Swamp has acquired a reputation for being a difficult place for opposing teams to play, and has regularly been ranked at or near the top of lists of top home field advantages and/or best game day experiences in college football. One of the major reasons is the stadium's design. Originally built in a shallow sinkhole, the playing surface is below ground level. Expansions have enclosed the playing area on all sides with steep stands, and the fans are within a few feet of the action. This traps crowd noise inside the stadium, which results in sound levels
