SAN FRANCISCO (KRON) — A billboard seen in San Francisco appears to warn people against moving to Texas. The mysterious billboard located at the intersection of 7th Street and Folsom, reads “The Texas Miracle Died in Uvalde,” and is accompanied by a menacing-looking figure wearing a hood and sunglasses.

Along with with larger message, the billboard also has the words “Don’t mess with Texas” crossed out and in the bottom right corner, reads “Don’t move to Texas.” No other information is seen on the billboard. According to a report in SFGate, the billboard at Folsom and 7th is leased to advertisers by FoxPoint Media.

While it’s not explicitly stated, the billboard appears to reference the Robb Elementary School shooting that happened in Uvalde, Texas, on May 24. Texas leaders have faced intense scrutiny over state gun laws since the tragedy that resulted in 21 fatalities, which included the deaths of 19 children.

Texas is a “permitless carry” state. The practice is sometimes referred to as “constitutional carry” by proponents — the law allows anyone who can legally have a gun to do so without undergoing training or background checks. Per current Texas gun laws, you only need to be 18 to buy rifles and 21 to buy handguns.

According to posts from Reddit users in Los Angeles, the mysterious billboard has also popped up in Los Angeles.

Texas has seen an influx of people relocating from California in recent years. Several major tech companies including Tesla, Oracle and Hewlett Packard have moved their headquarters from the Bay Area to Texas.

KRON4 News reached out to FoxPoint Media for information regarding the billboard but has not heard back.
