Trumpet Snail

My name is Jeff Hon and I am looking for a source for some Trumpet 
snails.  No I am not crazy, I keep them in outdoor barrels and ponds.  I 
live in Northern California and some time the the temperatures dip below 
freezing which has reduced or elimanated my snail population in the 
past.  I am looking for someone in CA who could supply me with a few.  
Any sources or information would be appreciated. None of the local (60 
Mile radius) sources have any.

Please disregard the above e-mail address when responding-instead use 
jcom at wco_com
