I've been to at least a dozen shows in CP and I've only gone home with two guns from there, both at the same price as the local shop or gunbroker w/shipping.
There *might* be some deals there, but they're few and far between and gone immediately, there's nothing left come Sunday, when I usually make it out there. I mostly go just to play with a large selection without the glass case hassle.
indy1500 wasn't packing many great deals either, too many people looking to buy which made it harder to get a deal.
I live about 15 minutes from CP. Every time I walk out of the CP show I vow to never step foot in the door again. I usually give in once every couple of years and go, but since I went to the last one definately won't be going. So to answer your question, NO it's not worth the drive from fort wayne.
