Air Canada's inflight magazine "En Route" has a neat puzzle type that kept
me busy for a little while on a recent flight. In a square grid, maybe
12x12 or so, a certain number of trees are placed in cells. You then have
to attach a tent to each tree, in a cell neighbouring it horizontally or
vertically, such that no two tents neighbour one another (diagonal
neighbours are also disallowed). Numbers beside and below the grid tell
you how many tents should appear in each row and column. It was a fun
puzzle, and I'd like to find some more.

En Route doesn't put their puzzle page on the web. Googling +tents +trees
+puzzle doesn't turn up anything, and I wonder whether this is a known
type of puzzle that usually features other objects I could search for
(i.e. En Route's puzzle editor changed it to trees and tents). Does this
ring a bell with anyone? Has anyone got a recent issue of En Route they
can copy a puzzle from and post it, as an example to others?
