Not a dam thing cause it was too freakin hot, even in the shop. But I did go out and buy the first of several a/c wall units that I am going to install at my shop ( going to try 15-19,000 BTUs to cool down a 600 sq ft shop thats pretty tall) so that I can work on my projects comfortably. Oh yeah and since elctricity is included with the rent, running all those window units isnt going to hurt my wallet anymore than usual at the end of the month 8)
