Back to the future

I'm re-writing a story of the future I drafted some 30 years ago, then forgot. An old friend brought the manuscript over from England recently. The title is "Cod's Roe". The idea seems good, but the style pedestrian. However, as I type it up, hoping to reinvigorate it as I go along, I'm not changing very much: mostly from past tense to present. Appropriate, huh?
