I've read that oaks can harbor the chestnut blight fungus without taking damage; hence the inoculum remains in the forest waiting for its real food.
Tough roots for sure! On the state lot (gifted by Gov. Baxter's nephew in 1969) near Merrymeeting Bay in Topsham, there are several American chestnuts. A white pine plantation was established in 1959 on 15 acres that earlier had been a market garden for about 20 years. We thinned the plantation early in 1989, and that fall I saw a 5' tall American chestnut growing in a skid trail. After 50 years (at least) under a plow layer, the roots still had sufficient vigor to sprout 5 feet in one growing season. 22 years later the tree was 11" diameter and over 50 feet tall, but now it's been blighted - dead above 15' and soon down to the root collar as well.
Welcome to the regulated world of gas cans. they are designed to prevent you from catching on fire from spilled gas. and they suck
And the irony is that I've spilled far more gas using the crummy thing that I ever did with the old "unsafe" ones. They're evidently designed so that one needs to employ both hands to use them (unless one unscrews the entire spout, which I'm tempted to do.)
