We did manage to find a close church to go to on Easter and then we decided to drive up to Oracle, AZ to see the Biosphere II. This was built for a project to see if we could create a new ecosystem (in space for example) and keep it self sustaining. Six people lived in the biosphere for 2 years, but it wasn't a complete success. It turned out that organisms in the soil were using up the oxygen too quickly and they had to end up pumping oxygen in to even out the atmosphere. It's kinda grown up now but still pretty neat to see the science behind it.
Funny side note ... we didn't take into account that restaurants in the middle of nowhere would be closed for Easter so we ended up eating Circle-K hot dogs for Easter dinner.
