Those gnats are a damned nuisance! I was out on my motorbike yesterday and it seemed like the entire area just south of San Huan Lu was one big swarm. It STILL feels like I have them crawling everywhere.
Remember that there was a couple of days like this last year as well, but I don’t remember it being this bad, or this early in the spring for that matter, but then again it’s been a very warm spring and with the drought many pools are low with no animals to eat the insect eggs, so I guess it’s just a natural occurrence.
