Shovel is very good for shifting the dugout dirt. Your bound to be digging where other diggers have left off and so will have an overhang...not good for a big swing pick...even a sharpened ( and hooked ) screwdriver is a
very cheap high efficiency tool.
Cut the head off a golf club ( from a thrift store )..good for a "surfacing" stick. Creek beds are pretty dry.
At this time, best suggestion might be to check the rain % predictions for Moody TX (WEATHER.COM) for the days your interested in..
Hal, it looks like Wed. Have to go see the in laws mon, and tue. If I get to go Wed I'll have to leave here around 4 30 or 5 am to get there by 9 am. I'm looking forward to doing some digging though. It's been way too long.
