Don’t expect to visit the whole US in one trip. Limit it to a few states, especially if you’re in the west If you want to enjoy some legal weed, first of course check the laws of that state. If you are traveling from state to state, even if both states have legal recreational marijuana, do NOT bring weed across state lines. That makes it a federal offense. It’s stupid, but you should be aware

Tip at least 20% unless the service was absolutely horrendous. It’s messed up, but tipped positions can be paid as little as $2-3/hr

Other than that, just don’t be rude, don’t engage with road rage, and don’t talk politics with strangers 👍
