No sweat and true. Alarm guys afraid to flow water/sprinkler guys afraid to set off an alarm. If'n you cain't do da otha guy's job right them don't do it a t'all. Since you went this way I recognized that many would focus on the procedure and I was addressing the results. Together we all make an awesome team. We should form a national all-stars company and immediately go broke while we ponde the issues while the trunk slammers do the work. Scary! Abort! Abort! Forget the idea.
