Funnel what ?

Found out last month that one of our competitors' on the North end of our network is pulling the plug.  Looks like they got taken over by xPlornet (I love xPlornet - when they "bought" our main competitor (Storm) we had a party in the office :-)) )... anyways we now have more towers going up, up the valley. One @ 90' on Highway 60 and a 50' (on top of a 150' hill) on Highway 41.  Working at about 40' on the Highway 41 location today and we were watching these really black cloud marching along the far side of the valley... then thunder, then something that sure looked like a funnel to me... The ground man (ground crew ALWAYS calls the shots) pulled the plug and we had to pack it in.  On the way home we hit a solid wall of heavy rain for about 10 seconds and then nothing. Strange.  Hope when we go back tomorrow that the tower is still there :-)).  Didn't intend to build out into that area (ever) but you some things you just can't say no to ;-)  Thank you xPlornet :-)
