Highly recommend going to see it. It's an incredibly moving experience. My grandpa was in the invasion and my brother (years later obviously) was in 1st infantry division.
Time in the market.
Roths are easy to set up, my son started working for us last year at 12 and we maxed out his contribution, which will be the plan until he's 18 and likely off to college. But, doing our best to imprint on him, to always put something away.
