How many Subway Cold Cut Combos go into an acre of timberland? (Here’s a hint: It doesn’t matter if you order a six-inch combo or the footlong.) Only a nuclear physicist could answer that correctly, right? Exactly. A nuclear physicist by the name of Peter Buck. Dr. Buck’s TALL TIMBERS TRUST has emerged as one of the largest owners of timberland in the Pine Tree State. And it’s all because Buck gave a college freshman (and family friend) named Fred DeLuca $1,000 and the idea to open a submarine sandwich shop in Bridgeport, Connecticut. That partnership has since manifested itself in 40,000 locations – and 925,000 acres of timberland.
