About 10 years late lol

What's up with the members that were "last seen" 8+ years ago but still show R2R supporter. Do those badges stick around or are those members still paying while inactive for years?

That's fair, guess I could've answered the question. My lights are on for about 12 hours a day. 2 hours on each end are super low intensity as they ramp up/down. Full intensity lasts about 4 hours per day.
