In this situation, you will be tried in Iowa, because that is the state where you committed the crime. It does not matter that you live in Michigan or that you went on vacation in Florida, and were caught there.
The reason is that section 2 of Article 2 of the U.S. Constitution obliges states to return fugitives to the state where they are being prosecuted for a crime.
This section also obliges states to guarantee residents of oher states the same legal rights and protections that they guarantee to their own residents, so you as a resident of Michigan, will have the right to a fair trial in Iowa, as if you were an Iowa resident.
Civilization developed around rivers because their water provided places to hunt and fish. Also as the rivers flooded the land around them became fertile. This allowed them to support farming.
