For n points placed uniformly at random on the unit square, suppose
$M_n$ (respectively, $M'_n$) denotes the longest edge-length of the nearest
neighbor graph (respectively, the minimal spanning tree) on these points. It is
known that the distribution of $n \pi M_n^2 - \log n$ converges weakly to the
double exponential; we give a new proof of this. We show that $P[M'_n = M_n]
\to 1$, so that the same weak convergence holds for $M'_n$ .
