Hundreds, maybe thousands, of snails seen along bike path, attached high on vegetation. Also seen in other parts of San Diego. According to this U of Florida site, "The white garden snail, Theba pisana (Müller), is the worst potential agricultural pest of the helicid snails introduced to North America....This snail was first noticed in North America in La Jolla, San Diego County, California, in 1914 (Chace 1915, Basinger 1923). It is established only in San Diego County, but has been reported both Los Angeles and Orange counties (Flint 2011). Mead (1971) reported an infestation in Los Angeles County in 1966 which was declared eradicated in 1972 (William A. Edwards, personal communication). The snails were found and identified in August 1985, in San Diego, California, at several localities in about a 10 square mile area. Hanna (1966) stated that T. pisana has been introduced into several eastern localities in the United States. However, there are no published records for North American populations outside of California."
