Signing Savvy, Your Sign Language Resource

I like this sign for walk the best. I never seen anyone do #3

That's odd; I've only ever been taught or seen #3. I'm assuming it's just a specific regional variance. I live in Massachusetts.

I've seen all three... but then again I've lived in in six different states.   I think they are basically regional variants... all proper ASL, I wonder?  #3 or a similar sign like it seems to be the one I encounter more often in my interaction with the Deaf community.
