moving to a whole new state...

For months my husband has been waiting to get hired by a company that has its workers leave town and go to another state. I at first was against is since we have a baby (10months) and I didn't want her being back and forth places. However Now Im being supportive and a few days ago he got a call saying he was hired ! We live in Texas the place where we're going is Iowa, 12 hours from us. We leave in a couple of days. My family isn't very exited they tell me to think about it. For instance, we don't have a specific address of where we're going to, all my hubby knows is it's Iowa. Has anyone had to do this ? Leave your home to go where you've never been before ? How did you manage ? I haven't even packed yet and honestly idk where to start.
