Lottery pools
One permit. Six shots at it.
Most lotteries allow one application per person, and a permit covers the whole group. So the way to win is more applications behind one trip. Six people entering The Wave takes the crew from roughly 4% to 22%. Whoever draws it, everyone goes.
The hard part was never the math. It is chasing five friends across a text thread to confirm they actually entered before the deadline. A pool does that for you.

Plans and pricing
Three ways to watch
Permit season runs summer to early fall, so Pro is priced by the year and one payment carries you through the whole season. What changes between plans is how many trips you watch and how fast we check them.
