Using abbreviations in URL - Matching Keyword

[Heydarian]

We have a website that uses /us/,  /ca/,  /va/, etc for URLs of the different U.S. states.

How much better is it (or is it at all better) to use /california/ or /virginia/ instead in our URLs to rank for searches that include the name of those states?

Nima,

I get thousands of visitors every day who use a two-letter state abbreviation as part of their query.  Not so much for Ohio or Utah... but definitely a LOT for states like California and Pennsylvania.

So, I would not be motivated to change.
