Are spacewalks popular in other cities for kids' birthday parties? They are really big here. My neighbors are throwing a party for their daughter's 7th birthday and have a Dora The Explorer spacewalk set up in their backyard. They are the perfect party entertainment. The kids are kept in an enclosed area and they don't need the adults to keep things lively. Jumping around and falling on other kids is tons of fun. I always like going to birthday parties with spacewalks. Skating parties were fun, too.
