Map I drew during today's work meeting. It's a local village geographically reversed. Someone with a very keen eye might recognize it.

I continue to be amazed at how bad ArcGIS Pro has gotten. No task is repeatable. You spend hours developing a model or work flow and then come back to it two months later and it inevitably fails. Trying to find ways to migrate some of this to other software but I'm no software hacker. #gischat

One of the many reasons I struggled to finish the #30DayMapChallenge was because we had to go pick up our newest family member, name still TBD. He's very nervous but we're working on it.

#30DayMapChallenge Day 30 : Makeover. I tried to redo my Day 26 #GulfofMexico shipping map that I was not satisfied with. I made it old style like my Day 24 portolan chart. This needs work that I don't have time to put in. At least I did all 30 Days 🫨 Thanks for tuning in! ❤️ #gulfofmexico4ever
