I really can't believe this conversation, I mean that it has been given ANY merit for running on the street! Like Moper said above, go for it. If you really want excitement, weld the spiders on a front differential on a 4x4! Yeah, done that too.
Tell you what I have done to two different trucks I had. Both had open front differentials. I put a spool in them. Unlock the hubs for street driving. Then lock one for off road....and if I needed to lock the second to get out of a jam.
Makes the steering way less effective with both locked, but it will work well to get you out of bein stuck.
