I have no idea where whoever wrote the BLM notice got those dates since they don't match 2018, 2019 and as has been pointed out, 2020. The correct dates from SCTA were published in November, 2019 sometime, I think, and haven't changed. Seems we are putting some trust in the BLM (HAH) rather than the horses mouth, kinda like trusting that nothing has changed in the salt over the years........
