There are only 600k private pilots in the US? Dang, that's a small group of people I'm thinking I should join. Growing up flying with my dad, off-and-on, I had no idea the numbers were so small.
Disclaimer: I hold a private ticket, and 10 years later still haven't found time to get my instrument or multi-engine. Life happens!
Airplane people are either very helpful or old curmudgeons; but mostly the former. Most are really happy to help someone get started. General aviation can use all the help it can get.
If I recall correctly, the parking area of the airport used to be packed with small single engine planes. Now, it's kinda empty.
