I have two from my pratice field:
First one happened a while back. I was going through my bag, and I knew something was missing, but I couldn't figure out what, since I throw my main discs and back ups at the field. The field is about 270ft long, and then there are some trees starting at the 275ft mark in the field. I am the only one that ever uses this field and I am glad, because I was walking among the trees, and I found a Star SL that I had thrown at least 2 weeks earlier. I can't believe it sat out there all that time , just laying on the ground.
In that same field , there is a row of thick bushes, about 3ft high, that run the length of the field and separate the parking lot from the field. These bushes are very thick, and like to eat discs.
I threw a Surge SS and the wind caught it, and it went in the bushes towards the end of the field. I don't remember if I looked for it or not. I tend to throw so many out there, sometimes I loose track.
3 months later, I threw another disc, and it looked like it had also gone into the bushes. This time, I went and looked for that disc, and as I was looking through the bushes, there was that Surge SS stuck in the bushes. I had to laugh, because some ants and put a bunch of dirt inside the rim, and were living in the inside of the disc. I was happy to get it back, and I couldn't believe it had been sitting out there that long.
