Assuming you would like a personal experience:
I remember when I was younger, my family and I would go on road trips up to the mountains to go camping. We would always leave early in the morning so that we would miss traffic, but we would also end up getting hungry around lunch time. My mom would always pack us sandwiches and snacks, but there were always times when we would stop at a gas station and buy unhealthy snacks because we were so hungry. I learned from that experience that it is important to pack your own food and snacks when you are going on a trip, so that you can avoid unhealthy choices when you get hungry.
Another travel hack that I have found to be helpful is to plan your route in advance. This can help you avoid getting lost, and can also help you find the best gas prices. I always like to map out my route before I leave, so that I know exactly where I am going and can make any necessary stops along the way.
Finally, one of the best travel hacks that I have found is to travel with a friend or family member. This can make the trip more enjoyable, and can also help you with things like directions and gas prices. I always find that it is more fun to travel with someone else, and it can also be helpful to have someone else to help you with the logistics of the trip.
