Had early tee time. Paid regular Senior Rate. Found course is being aerated with tractors & maintenance personnel all over. Workers driving tractors right up to and behind players (without any courtesy) and without moving tractors away from fairway in front of players teeing off. Big mud clods all over first two fairways making those two holes UNplayable. Staff should have advised us of that condition. When we complained at the end of nine holes we were offered a 25% discount ticket for future play which was not applicable for Senior Rate. In other words, we got SCREWED. We drove across town to play Pacific Springs GC that's why we continued playing otherwise we should have walked off and demanded a refund. Where's the COURTESY for players?
