Hey y'all, I'll be in Paso Robles/Atascadero for a concert on Saturday Sept 11. Would be nice to make a friend after the show  

Their are NO providers listed by TER in either Paso Robles or Atascadero.  The nearest city would be San Luis Obispo.  Here's a list of SLO providers:

Most of them haven't had reviews in a long time so I'd rule them out.  The first three would be your best bet.  The third one's last review is 10 months ago.  The second one has only two reviews.  The first one on the list would seem to be your best bet.  Check her reviews out and go from there.
