Hi Alyssa,
Have you thought any further about meeting up at City Center Bishop Ranch? Google Map shows it's still under construction. Or is the Map out of date. Erik (Offroading is Fun) thought a Saturday in Mid-May would be nice. That would work for me if I can convince my other half.

You must be looking at an out-dated map. The City Center in San Ramon opened a few months ago.
