This might be cheating because I did not actually take my friend all the way to the airport but that is because how drastically Denver has changed.
Anyone that has lived in Denver longer than 5 or 6 years knows how much it has grown. I have lived here almost 10 years and have seen monumental changes. I can’t even imagine what people that have lived here for 20, 30 or 40 years have seen.
One big change is new light rails to opposite sides of the city, making it much easier to travel from one end of the city to the other.
The most convenient train is the new train out to the airport. Denver’s airport is very far from the city and in the past getting there was quite a pain.
A friend’s step father died and he had to catch a flight quickly. I called and offered to take him all the way out to the airport, but he said just to the train station. Not sure that actually taking someone all the way is worth it anymore. The train there is no traffic, so the trip is more convenient and timely.
