   I typically keep a few cans of it in our garage.  I have not needed any   
   lately, since the Monte Carlo isn't leaking it anymore.     
      
   A few weeks ago, it was too hot to ride.  I won't ride when the temps go over   
   95 degrees.  It isn't fun when it gets that hot.   
      
   I had to go up in the attic last weekend to adjust the dampers that go to the   
   upstairs rooms to get the air flow evened out.  I did it early in the morning   
   before it went up to 100 degrees outside.  I would be willing to bet, the   
   attic gets to around 130 degrees on days like that.  Takes you breath away and   
   instant sweat.
