   I havn't had a need for it either, but this leak appeared out of nowhere   
   when I began to move the Z around.

   Lucky you don't live in Texas. Its always too hot to ride, except for an   
   early morning or late evening cruise. South central Texas, unlike the east   
   coast and upper midwest, cools to 70+ at night and warms up to the day's   
   high around 5pm, then begins another cool down as the sun sets. If it was   
   anything like northern Illinois when I was growing up, I wouldn't live   
   here. You'll know that it's going to be a hot one when the wind shifts   
   from a westerly flow to a southerly or south-southeasterly flow during   
   the summer.

   I had DirecTV out here yesterday, installing a new sat system. The   
   'helper' tech got the job of attaching all coax to the dish that the   
   'senior' installer put up the roof, then he got the 'attic' job of running   
   coax. I didn't envy that youngster that job one iota. Been there too many   
   times.

   Without a good roof vent system, it gets hotter than that. Our house has a   
   peak-vent that runs the entire length of the house and that helped some,   
   but I'd venture to say that it still gets upwards of 150 up there.
