I know what you mean about "being like a desert".  If I had a big shade umbrella, I would certainly bring it.  
 
Last time, my broom skirt was a popular shade spot for the dogs, heh.  (Or was that the month before?) 
But, it looks like we're having cooler weather.  I think we will all enjoy it more so I'm looking forward to it. 
FastEddie - I know!  This one seems to have come around so quickly!  
I need to wash Bodhi and RSVP on the Meetup.com site. 
We look forward to these so much as there are no small breeds at our neighborhood park up the block.  Hubby and I have decided to get even more strict about letting Bodhi come close to the others.  Larger puppy paws tromping on Bodhi scare me. 
The only other option we have is at Ahimsa's Saturday 20 pounds and less Puppy Play hour for $10. 
Bodhi is too shy to play with the rowdy ones and we get separated to one or two other dogs that are younger and just as shy that he is able to play with. 
*Daydreams*  Someday, if we get a house with a nice yard and TREES, we'll host the meetups.  Plenty of lawnchairs and a picnic table.  A canvas tent with an outdoor heater for the dreary days.  Maybe even have potluck....*continues to daydream*
