Public Service Announcement:
I recommend going to CourthouseDirect(dot)com and signing up. It’s free as much as signing up for anything on the interwebz is free. They’ll email you a monthly list of new o&g courthouse filings. Their only drawback is that for whatever reason they don’t do Lavaca County.
Having said that DYOR but there’s probably not a square inch of unleased property in the M Muldoon Survey. Rosewood and Flat Land. High hopes around Flatonia.
