All I can remember is after coming out there were some steps leading down to a very open area where folks were sunbathing on the grass. I was so taken by the plants that's what I really remember. The bldg. was white and did have a dome maybe that's where I was. My son and family got tired of waiting for me cause I took my time and really wanted to remember a lot of names of plants. I should have taken pics but I don't think they allowed that. Anyway it was a great experience.
