FT LAUDERDALE (CBSMiami) – State forestry workers are trying to get a handle on a brush fire burning north of I-75 and a west os U.S. 27 in the Everglades.

“There’s a lot of burnable fuel out there, it just spread, meandered through these Everglades,” said Scott Peterich with forestry service. “It’s hard to get around it. Our objective is to keep it confined to that area so as it burns, we just don’t want it to get out. ”
