I have talked this over with a particular Ph.D student who suggests that the
"wide-guage" tracks may something present in somphospondylans due to
modifications of the femur.  Wide guage and/or anti-pigeon-toed tracks may
actually help to identify sauropods as perhaps somphospondylans.  

Thanks for the great reply (including the explanation of the the nature of
the tracks' location in urban settings).

Have  a great day.
