Take it with a grain of salt, Redbeard. Most of the people on this site are great people. One guy, made everyone's misfortune curious to some of the people here. They are just watching out for each other now. We're a team, i guess you can say.
Played a few courses in Minneapolis but none of them I played had water that I would feel would be loaded with discs. Gotta throw really bad to have multiples in the ones I played. Try Craigslist in your area. There's been a few times where people had some good stuff for real cheap in your area. Search out all variations of what people call disc golf. it's the non-avid ones that we'll have the 8 discs for 30 bucks deals and stuff like that. They just might list it as "disc golf", "disk golf", "frisbee golf", "frolf", or something by brand "innova", "discraft", etc. They ones who don't know what they have usually have the best deals.
Good luck and sorry about your car. In my last car, kids broke in, went through my backpack and the rest of the stuff in my car and walked off with two of the 30 CDs, my Family Guy Season 3 DVD box sets, and the ashtray with all my coins in it. Kids! If they were smart, they would have throw everything in my backpack and stolen my $200 headphones too. They unrolled the cord and found no mp3 player and left the headphones. Pissed me off because they went through all my cds and only took a couple. It's not my fault they didn't know who Cowboy Mouth and the Wonder Stuff are. I was more upset that they were being selective. Made it not worth filing a claim.
