St Petersburg - Clearwater International Airport (aka PIE) was constructed by the US Army in 1941 as a training base for pilots heading off to war. After the war, the airfield became a commercial airport called Pinellas International Airport (named after the county), and the main runway was extended north into the bay. Later, commercial jet traffic was consolidated to Tampa, meaning PIE was used mainly for charters, private planes, and the coast guard.
Today the airport is still home to Coast Guard Air Station Clearwater, considered the largest and busiest Coast Guard Air Station in the US. The largest commercial airlines at PIE are Allegiant Air and USA 3000, which serve a variety of northern cities, while a few smaller airlines serve regional destinations and come Canadian cities. United Parcel Service also has a large operation at the airport.
PIE has 13 gates that handle about 750,000 passengers each year. Parking is $13 a day, and rental cars are available. The airport has one restaurant and one gift shop/snack bar.
The Suncoast Beach Trolley runs some 18 miles along the Gulf of Mexico from downtown Clearwater to Pass-A-Grille, through numerous little beach towns including Indian Rocks Beach. The cost is $1.75 per person whether you are going one stop or the entire route; $4 will get you a one-day unlimited ride pass. In Indian Rocks Beach, there seems to be a stop about every two or three cross streets, including stops directly in front of many parks, government buildings, and big restaurants.
You can pay as you board, using the automated fare boxes next to the drivers. These boxes take $1, $5, and $10 bills along with any coins, but do not dispense change.
