The concept of adding the sprinkler's on/off switch to the observatory opening and closing tasks looks like the best option to me.   From: Bruce Hugo via Utah-Astronomy <utah-astronomy@mailman.xmission.com> To: "utah-astronomy@mailman.xmission.com" <utah-astronomy@mailman.xmission.com> Sent: Tuesday, June 30, 2015 1:16 PM Subject: Re: [Utah-astronomy] Sprinklers (Was: Wow!) I've never operated the valve nor know of its location (guess I need to attend more star parties!), but just a thought: Properly mark the valve positions on/off. <======= Important. To make the valve operation second nature, tie the valve adjustment (on/off) to a major action such as whomever opens the access gate must turn the valve to off.  Whomever locks up the gate must turn the valve to on. Or, because of it's high priority (wet astronomy equipment is frowned upon) a task could be added to the Observatory opening and closing tasks which is a very well thought out deliberate list. Hoping to help!
