Hey fags, Belgianfag reporting in.
So a friend and I are planning a 3 week trip to the US next summer. Below is a provisional route for a couple days NYC and about a 2 week car rental travel through the West Coast -> North to South.

1) When/where should we buy plane tickets, and are these long flights susceptible to changes in hours/dates?
2) When driving down the West Coast, is it possible/worth it to bring a tent and camp at some places down the road?
3) Any places recommended that aren't in my list yet, or some in my list that aren't worth it?
4) General tips and ideas are appreciated.

So, we will be looking for a flight to NY out of Brussels/Amsterdam/Nearby german cities.
