We're tree people, so seeing this giant was a highlight of our Clinton to St. Charles trip last July. Well worth stopping for an hour or so and just sitting at its base, soaking it in.
By the way, the correct spelling is bur (not burr) oak. I found this in the Audubon Field Guide to Trees: "The common name describes the cup of the acorn, which slightly resembles the spiny bur of the chestnut."
