Doing a Music Concert at a Winery 200-1,100 people - I have been asked to do a Summer Concert Music event at a Winery. The person in charge says, "we will have 200-1,100 people - never sure". "... worse thing is you sell out". I am nervous I will not have enough and they have a ton of unhappy customers - or I will have feed for 600 and no one shows up OR IT RAINS. Any feedback, guys? We have fed a couple hundred - and I have the staff for help - friends, family, etc. Input?
