Yesterday we were coming back from our ride on the first sun-break in an awfully long time, through the flooded fields, and we saw two deer bounding across a field, then across our road, then into the next field... and then they had rather suddenly stopped and walked slowly... we wondered why (deer interval training?) until they got to the edge of the field and stepped out and the mud all over their hooves showed exactly why they were unable to proceed. I'm glad none of 'em actually got sucked down... and whether or not they ever do. I can't help but think a deer could break a leg in that stuff.
