For the past several years I've been a licensed engineer in South Dakota, North Dakota, Minnesota, Iowa, and Ohio. These states are exactly in close proximity to me and vice versa.
About a month ago my Minnesota license was up for renewal. I didn't. At the end of December my North Dakota and Ohio licenses will be up for renewal. They won't be. Of the five, I'll only keep my South Dakota registration current and active. It's my home state and my first.
In order to keep options open I've made application for engineering license in Washington, Oregon, and British Columbia. I was thinking I might do a little engineering on the side during the wetter, less daylight months. This would be extra cabbage for travel, gear, bikes, and maybe even the retirement fund. Like I said, a dude's got to keep his options open.
