We went to the Lyle Lovett concert at the Portland Zoo this summer. Very fun! Portland has a lot of great outdoor concert venues. We hope to explore more next summer. The Lyle Lovett concert was great! Beautiful evening with fabulous music and happy people. Our advise: arrive early to wait in line and then nab a spot on the grass as soon as possible - it filled up and overflowed quickly. We brought a quilt to spread out and sit on, low chairs, bottled water, and some simple picnic food. We purchased wine and beer at the zoo venue. Our group took turns getting up to walk around while the others stayed to preserve our space. Perfect!
