what do you mean by too wet? get a row boat go out there and dig! You could always use hip waders and carry a long stick to see how deep the mud is...take a partner.
Sounds like a plan, All I need is you up here to help me push a row boat a half a mile down the railroad tracks, But before that we have to get it up about a one hundred embankment. LOL, let me know about a week ahead of time to build up my beer muscles!
