Brian and Brad are completely right. Waivers are mostly designed to act as a deterrent for frivolous lawsuits required by every insurance company, for almost everything.
I know there are people that don't participate in Flock events because of waivers. I also know people who don't participate in other events for various reasons as well. To each there own--you will never please everyone.
As for the specific reasons we have waivers, it was my call, and I will take any complaints about it.
However, if one has an issue with Flock's waiver, they should really read the terms they agree to by using pretty much any form of technology--the agreement to have a simple landline telephone is more limiting and in depth than Flock's waiver.
If one is worried about the information we collect, that's a personal decision, but I have a feeling that if anyone really wanted that info it could all be found in public records.
If organizers of other events don't want to have insurance and waivers, that's on them. I (unfortunately) live in a world where people sue--especially if they think you have something of worth (even though the value might not be what is imagined).
Personally, I don't hold many liquid assets, I do hold some assets which I care enough about to not lose in a petty lawsuit because someone did something stupid on a ride I organized. Luckily, there hasn't been any issues with ride events in Pittsburgh (that I know of), but I am not willing to gamble everything I've worked for on the chance that it will stay that way.
