GLD snowmobile drags

[slow90z]

I see there is a radar run on the 30th, Can someone tell me if i need to run a teather, at first i saw it was a requirement, but now it says trail sleds are welcome, mine never came with one and i need to know if i should go buy one, also. How long is the track going to be. Thanks

A teather is nessecary when we run side by side drags,not required for radar runs(single passes) get one,it never hurts to have it anyways,and they are not alot of $$
We will be running just a hair over 500 ft (533ft to be exact)
Trail sleds are more than welcome.
