Thanks so much for the information Korash. I'm glad to hear there are some fellow GIS people here. I look forward to hearing from them. If anyone reading this has personal suggestions to their favorite tutorials, or helpful links/videos that may lie outside of this site, please feel free to share them.

Funny you mention the river police, because as I looked at some maps when I first found the site, I was laughing at some of the river placements. Never even realized it was an area of expertise. Enjoyed the laugh I got from perusing the rivers though, that's for sure. Thanks again for the information and comment.
