Let me tell you that the other AmeriCorps members were amazing ! Although we only spent a week together training , we really came together as a family , and its nice knowing that you have a support group that will be doing the same thing as you . Also , St. Louis is a pretty cool city , especially the arch ! As silly as it seems , it was cool going up there , and then checking out the museum downstairs . So I flew into Detroit last Saturday , and it was rainy and gloomy .

Question: What 's a possible reason the writer flew into Detroit last Saturday ?
Answer: Because St. Louis is a pretty cool city .Because they live in Detroit .None of the above choices .Because it was rainy .
