If trains are their meat and drink, what could give them more pleasure than to actually ride one? And we’re not talking the subway here. Book them for a trip across America on Amtrak, whose lines still have such romantic names as the Sunset Limited (Los Angeles – Orlando), the Empire Builder (Chicago – Seattle), and the California Zephyr (Chicago – San Francisco). Amtrak’s Explore America fares make this an affordable and enjoyable gift for any train aficionado.
