What is the most popular destination from each start station?
In the last exercise, you created trips_dec, which consists of the total number of trips grouped by start_station and end_station in descending order. This gives you an opportunity to calculate the most popular end station for each start station. You can do this by simply extracting the first end_station for each start_station.
trips_dec is available in your workspace.
