This weekend, take your promotional bags to the Atlanta Jazz Festival in Piedmont Park. Expect to see large crowds and have to park pretty far away. Since you'll be walking into the park and staying for hours, stash necessities in your promotional bags.
Bring an umbrella or light jacket with hood, since rain is expected. Also put bottled water and snacks in your promotional bag, since food will likely be expensive. Don't forget sunglasses and a visor, sunscreen, and antibacterial hand soap or wet wipes. Include a plastic bag to use for trash.
Wear comfortable shoes, layer, and get excited about all the live music.
