Welcome to the forum. You'll find the Pentax gear an excellent fit for those Michigan out door activities
.
If you haven't done so already- take an opportunity to research how to recognize which lens designations include what level of weather sealing protection.
Ohh, and I recommend to be just a little cautious around Pentax oriented resources such as the forum- because although some people may complain that the Pentax stable doesn't have a very large lens selection, I find that they have quite a few choices that could easily prompt LBA lens buying addiction.
