Bad experience with a hot headed security person, if it continues I will not be returning. I have been here many times over the past 8 years with family and friends. We always had a great time. Until last week at the Santana Concert. There were young security people patrolling the isle in the the lawn area. I was standing/dancing on the side of the isle with my husband directly in front of me and there were other people lined up in front of him and behind me as well. The security people kept coming up behind me during the concert and tapping on my shoulder rather hard, telling me to keep the path clear. I was not in the path; I was on the side of it and apparently where I was standing was OK because they did not tell me to move nor did they tell any of us standing on the side to move. Each time I just nodded and they continued down the hill. They came by taped on my shoulder three different times. I was standing in the same place (on the side) the whole time. So I was physically interrupted while I was enjoying the concert 3 times for apparently nothing! I felt harassed so I stepped out onto the path to see what was going on and an older security man came flying up the isle and got directly in my face and yelled "do you have a problem!". He screamed that twice in my face! I did not say a word because I did not want to provoke him, he was very hostile! They should not have people like that working there. First I was encroached upon with the shoulder tapping; then I was verbally attacked! Mind you this is a Santana concert, most of the attendees were in their 60's including me, ridiculous!
