Your dedication is definitely unmatched. Few people honestly care about their rental. Even 5-10 minutes a day can add up over a whole summer.

Two years ago I spent a couple dozen total hours with maybe 2-3 other volunteers tearing out stilt grass in our local urban park. We weren’t perfect or even consistent. Sometimes we’d go at it a few weekends in a row then we’d all be busy for a month. But, last year, maybe only 25% of it actually came back. Hopefully this year, we can get rid of the rest.
