We're a bit more set up for rain up here so there is a lot of water around, but no significant flooding. The bridleways are rather messy but that's part of the fun. I've pretty much retreated off road for the last few weeks. If I'm going to get wet and muddy anyway then I might as well go and get properly muddy*
I'm getting a bit concerned though as I have a week long tour booked in mid-March and I hope the weather will calm down a bit before that.
*Also in the winds we're getting I figured that wide flat bars would give me more control than the drops.
