Did you ever notice how much more powerful the minus sign is than the plus sign? You add a plus sign to a number and nothing changes. It doesn’t matter how many plusses you add, still nothing changes. But add one minus sign and everything is different; totally opposite. Add another minus sign and it all changes back. Every minus sign has an effect. Now that’s a powerful modifier. Not much to report. Nice weather. Lots of work. The Park is full.
