This was a great tour with different features and narration than the hop on hop off tour during the day. It is difficult to find the starting place, so arrive early and ask around. There's a sign that says Big Bus, but it doesn't indicate it's where the sunset bus starts. The worst experience was that MANY tree limbs smacked people on the upper deck as we drove by. There was really no way to avoid them without literally lying on the seat. If I had not had on glasses, I probably would have had serious eye damage. Not sure if it's the City's responsibility or the bus company's, but someone must trim those limbs!
