We'd be remiss if we didn't start this post by saying that Unfair Park is not an entomologist. Not even close. That being said, looking at the address of locations being sprayed to combat West Nile, we think we've noticed a pattern.
Mosquito control measures this year had focused on North Central Dallas until the announcement of today's and tomorrow's sprayings in North Oak Cliff -- for an "abundance of mosquitoes," not necessarily West Nile, according to the city's notice.
Now, as you can see from the map above, the mosquitoes have begun a march to the southwest. To what end, we can't say for certain. That doesn't mean we don't have our suspicions.

Again, we can't say that Dallas mosquitoes have a genetic mandate to gather at that pool, that so many generations of the bugs' ancestors have told them of the wonders of the pool and its consequence-free promised land that their descendants, salmon-like, can't help but make the pilgrimage south.
We can't say any of that. But we'd advise you to check out the map for yourself.
