The speaker was discussing a contract that was particularly difficult to draft. It is a nice mashup of “rough (or tough) sledding” (difficult or turbulent period of time or undertaking) and “slow going” (a state of slow or arduous process). Both idioms refer to a difficult process that is slow, tedious, and difficult. The speaker also might have been thinking “snow sledding”, given the unusually hot temperatures right now. A big thanks to Donna Doblick who confessed that she was indeed the speaker and for sharing this one. It happens to us all, Donna.
