Ryan,
As a high school student I deliberated between LA and Agronomy (in Turfgrass and Soils) back in the same days as Tom, but followed the Agronomy route getting boned up on soils, soils, and soils, and plant physiology with Turfgrass studies under Dr. Beard at Texas A&M, working in the turf plots, with work in the USGA soils lab under Dr. Brown. For me (and that's just me) a great foundation to approach gca.
Then like Tom joining a great architect in Pete Dye, someone who is more in tuned to turning on the machines in the morning and throwing away (literally) the chicken scratch penciled layout plan.
And like Tom said there's alot of ways to approach getting in the business. Getting your hands, clothes and boots muddy and dirty, and smelling diesel in the AM (well you should fill em up at the end of the day, esp in winter) aint a bad start.
