Several thefts and car break-ins have occurred recently at the SF Boise River, as reported by Erik Eikanger at Idaho Angler.  One IA customer had a number of expensive rods and reels taken from his vehicle.

Several thefts and break-ins (smashed windows) have also occurred at trail heads in Boise, so the same precautions apply when fishing on the Main Boise R.

• Lock your car/truck when on the river
• Keys behind the gas cap-- first place thieves looking to access your car will check.  Do something different.
• Be aware of who might view you as you leave your vehicle 
• If possible don't leave gear visible in your car or accessible
  (e.g. truck bed)
