As a follow up to the loverly wind at state TT in WI today, I must say Zipp disks can really fly. In fact, i saw a racer attempting to put his stead away, when his zipp disc, which had been removed, decided it wanted to have another try. Those claims about zipp disks have lift in certain winds are true. The one i saw flew through the air at least 30 feet, bounced and went another 10 through the air before the owner could retreive it. Would make a great marketing ad, no??
