Clamming? 1/7/12

Hello,
I wanted to take my family clamming tomorrow as there is a negative tide - however I am not sure where to go!  I live in Castro Valley so anywhere that is within a 90 minute drive or so should work out fine.  My father (who is Korean) is really excited about the horse neck clams but would be happy with getting any kind of clam. 

Any suggestions on where to go and what to bring would be really appreciated. 

Thanks

Try "Lawson Landing"...

Heading to HMB as we don't have a boat for all of us... am going to try on the beach next to the jetty on the far right side (The area past the warehouse area).  Hopefully this area will produce.  If anyone is out there, we will be there around 1:30-3:30. 
Thanks!
Daniel
