Draw & harvest

Draw odds, harvest rates and season dates are next.

The state agencies publish them — locked in PDFs. The parsing pipeline is the next data milestone, and when it ships, this section fills in for every unit at once, free, with a link to the query that computed it.

How these numbers are made

public_land_pct = public_area / unit_area
landlocked = public ∖ reachable(roads, corners)
remote = public ∖ buffer(roads, 1 mi)

Computed, not curated: no paid research team, no opinions dressed as data. If a number looks wrong, file an issue — the fix ships for everyone.
