All of the below..
Here in the Los Angeles area, SoCal Airgas carries it, at least in larger
quantities. I don't know if they would fill a small dewar you bring, or,
more to the point, if they would fill a ice chest or equivalent (i.e.
something that doesn't look like a standard dewar). I can almost guarantee
that if you call them and ask if they'll fill your bucket, they'll say no.
You'd have to show up, look rational, and ask.

You could try the places that carry Dry Ice, but it's really a different
business.  Dry Ice might be another way to try cooled secondaries for lower
resistance.

If you know someone at the local college, they'll usually have a source
where they can fill your container.

Lots of industries use LN2 for refrigeration (food processing, biochem,
etc.)  Sometimes a bit of asking around will find someone with a big bulk
tank, and the necessary plumbing to draw some off for your container.  You'd
be surprised... ask your friends.
