😷 Wear a mask as you're coming back. I'm posting these with a historical intent. Links where possible, and let me know if your local is missing.
NOTE: MOST AGENCIES ARE ASKING FOR ESSENTIAL TRAVEL ONLY -- MEDICAL AND SUPPLY RUNS, JOB TRANSIT FOR THOSE WHO PROVIDE THOSE SERVICES. STAY HOME! EXPECT DELAYS AS THEY RUN CRITICALLY LOW ON STAFF.
Many agencies are requiring you wear a mask. Most ask you board from the back, and are putting limits on passenger boarding. Mask requirements are marked with "⚠️" and are because of state orders.
If the agency has a pass app, please pay for the ride through it -- it helps the agency!

Further reductions and mask requirments are hitting. I'm posting these with a historical intent. Links where possible, and let me know if your local is missing:
NOTE: MOST AGENCIES ARE ASKING FOR ESSENTIAL TRAVEL ONLY -- MEDICAL AND SUPPLY RUNS, JOB TRANSIT FOR THOSE WHO PROVIDE THOSE SERVICES. STAY HOME! EXPECT DELAYS AS THEY RUN CRITICALLY LOW ON STAFF.
Many agencies are asking you wear a mask, board from the back, and are putting limits on passenger boarding. Mask requirements are marked with "!!!" If the agency has a pass app, please pay for the ride through it -- it helps the agency!
