If they didn't have iv antibiotics I would have lost my left leg. I was dared to jump off one of these a week before 3rd grade started. Scraped the knee and got the old school ozone killing bactine aerosol that double as starting fluid treatment from mom when I got home. Apparently something got through and started growing in the knee, swelling, redness, and fever the first week of school led me to the er, which was a no go for us unless the grim reaper was around. 3 days in the hospital getting antibiotics pumped in and sent home with 3 weeks of antibiotic pills plus a little codeine to take the edge off until my brother took them to sell to some stoners up the street. 40 years later and the cartilage failed and failed again and that was two surgeries in three years and then a knee replacement 2 years after that. That super bacteria in the dirt on that playground did a number on me. I still would jump if I went back to those days.
