As I walked in via Trafton Road, Thursday morning, hammering sounded from the area behind the brick buildings, then vehicle and machine sounds.
A fire engine tooled around the park (I saw it three times) and I encountered five (5) city dump trucks, also, 18 ‘regular’ trucks (one of which appeared to be the department’s noisy, spewing M56 745, but I wasn’t close enough to confirm that or, luckily, to have to breathe its exhaust).

Crew attacks an tree trunk with chain saw(s) 27 February 2020.
Across from the children’s play equipment outside the zoo, all you could hear was a chain saw. Don’t know if another living tree was freshly felled or whether the crew chose to destroy a fallen tree trunk that lay well back away from the roadside. Left alone, fallen trees provide homes to numerous living things (insects to mammals), and it breaks down with time to enrich the soil for new life. – Rather than responsibly caring for life in this precious park, the city chooses rather to snuff life out.
