Due to the latest severe weather event, however, the frequency of people asking has spiked.

Marley Maheno owns ACA Clothing as a side hustle to his day job in IT.
He and his partner, Brooke, work from home on the T-shirts, which are printed on demand.
Maheno explained ACA Clothing received requests for all sorts of apparel, including schoolwear, sportswear, memorial T-shirts, and other special interest requests.
He said he designed the "Is the gorge open?" T-shirt about a month ago after a resident thought it would be funny to wear it in the Far North.
"It wasn't my idea, Grilla-Tactix owner Reti Blair wanted it done, so I made one and put it out there on the website," Maheno said.
"Since then we've sold about seven."
Maheno said he'd received all kinds of requests for local colloquialisms over the years, like "Any scallops on the beach?", and "Is Kaeo flooded?"
