A big thanks to Jim and Steve. You've been a big help and I appreciate it.
Mike, There just hasn't been many areas to dig around here lately, but I made the best of one small area on the edge of a bayou last week.
How have your digs been going?
Best of luck on the next dig to all the helpful people here. Marvin
