When I was in 5th or 6th grade, Brooks & Dunn (IIRC) played the Dubuque County Fair, and the Hell's Angels were there in colors watching from the non-paying edge of where the concert was held (near the 4H Chicken & Rabbit show barn if you know the fair). My friend and I were also in that area, and both wearing Wilwert H-D shirts, as we lived nearby Wilwert's old location, and hung out there.
We were standing against the chain-link fence, watching the concert, near their group, when two of them walked over to us and said, "Hey lil brothers, wanna see the concert closer?" and then proceeded to pick us both up and throw us over the 6' fence, and we skidded down the gravel and grass landing area... and got to see the concert closer.
