In response to the earlier comment about returning discs you find in the pond/creek/river whatnot I completely disagree. I swim for discs starting in March each year and just stopped swimming last week. I will text or call the owner of the disc if there is a number. Most times THEY offer to pay a small reward for me finding it. I live in South Dakota, the water temp was 38F...... You tell me I don't deserve something for my time and searching? I have made dozens of friends by texting, then selling back discs ($5). Just my opinion
