2. You Didn't Tell Anyone
If you don't tell anyone where you've gone or when you're coming back, how can they organize a rescue—or even know when there's a problem? Explain all the details to someone responsible. Better yet, write it all down for them. Tell them exactly where you're planning to go, where you'll park your vehicle, what route you'll take in the wilderness, and when you expect to return. This way, if you don't make it back on time, a local search and rescue team can be mobilized quickly. Fast deployment means they will have a much better chance of executing a happy rescue instead of becoming a body-recovery mission.
