Hmm.. I liked some of the food they used to have at the assemblies and conventions. Half-frozen orange juice, danishes, and roast beef sandwiches, especially. My family was too poor to take expensive vacations, but a lot of years we went to a DC in various other cities (even though it was frowned upon - my mother didn't like the place we were assigned to), and made a weeklong trip out of it and saw some nearby sites, some of which were good times. It sucked being a kid at a convention where you didn't know anyone though.
My father was also a pretty good guy and tried to organize events that the local kids would enjoy. He also was sometimes reasonable about things, letting us kids do things that were discouraged by the WTS. For example, I was allowed to play on a sports team in high school, and we tried to be kind of quiet about it at the hall since no one else from my congregation went to my high school. In sort of a mixed blessing I had a little bit of success and was featured in some local newspaper articles, so people kind of knew about it. I had to quit for a while but then was able to rejoin. It was one of my favorite experiences of my entire childhood, so I'm glad my father didn't take a hard line on that and also I'm slightly glad for "headship"; if it were up to my Mom, I would have never been allowed to join.
