Medic, welcome aboard, check out our website, IllinoisBowfishers.com for further info. Also, this weekend we will be down in your neck of the woods at Rend Lake on Saturday evening. We'll be there at 6:00 PM for a BBQ down at Sailboat ramp. Come out and join us and you'll have a great time and probably learn a bunch. Back to one of your questions, yes, I've shot both bodies of water that you mention and will be happy to share what info I can with you. Bighead is excellent smoked and gar is a favorite of some of our bowfishers so I'm sure they will share recipies with you.
