Is there any public location close enough to use my Tube to get to a bridge?

I'm not familiar with fork but make sure you pack you Off alligator spray.

Several places

Sirjet take a look at the east end of the Hwy 515 W bridge. There's access from the north side of the highway at that location. You'll be right at the bridge and pretty close to the main creek channel.

Several bridges have boat ramps near them..2946, both 515 bridges, 154. Bridge fishing has been off since the heavy rain, but should return back to normal once the gates close and the lake stabilizes.

And he IS serious about the Gator Spray...........lol....lot of pics of gators out there.

You can access Little Mustang creek on Hwy. 17 right next to the bridge on the west side.

+1, been launching there for years. Be sure to pay the launching fee of $5, put it in the box on the road to the ramp. In his shop Joe sells many types of lures and soft plastics, many of which he makes himself.
