I want to put some slogan signs on the guardrail around the basketball court. What is appropriate?

the f-1 race must be held in a special stadium, and there are very strict requirements on the length and width of the special stadium, road conditions and safety measures. Generally speaking, the dedicated stadium is annular, each lap is 3~7 kilometers long, and the total length of the track should not be too long, which is 35~32 kilometers. For safety reasons, wide grass or sand is generally laid on both sides of the track to separate the audience from the track. Nowadays, in many official competitions, the track in Morocco is the shortest (3.328km) and the track in Spa in Belgium is the longest (6.94km). FIA stipulates that there are not too many long straights in the stadium, in order to limit the high speed and avoid danger. Generally speaking, for a standard F-1 stadium, the following equipment is essential:

track-7~11 meters wide and 3.~7. kilometers long. In order to avoid excessive speed, many curves must be set.

Start and finish straight-12m wide and 25m long. Two racing cars can be placed side by side, but not too crowded.

stands-need to be separated from the track by barbed wire and 1.2-meter-high railings.

cameras and TV towers-used for TV broadcasting.

big screen TV-placed opposite the stands, so that the audience in the stands can know the whole game.

safety personnel observation station-located in a relatively dangerous area, for safety personnel to keep the runway clear, handle various accidents, and send warning signals to drivers of potential dangers.

helicopter-prepare for emergency rescue of injured drivers.

medical station-a protective place next to the repair station, with operating room and emergency room.

repair station-each team is equipped with one, which is a permanent facility.

sponsor reception stand-located on the high platform behind the repair station, overlooking the repair station.

paddock-parking place for transport vehicles and campers.

competition control tower-located on the second floor of the whole control tower, overlooking the entrance of the repair station, where the commander gets in touch with the safety personnel through the radio device to control the competition.

most of the F-1 stadiums are located in Europe. During 195~1995, 58 F-1 competitions were held, of which 47 were held in five continents (7%); 125 times in America (22%); 24 times in Africa (4%); 13 times in Asia (2%); Oceania 11 times (2%). In Europe, the most F-1 competitions were held in Monza 45 times, Monaco 42 times, Zan Dewater 3 times in the Netherlands, Spa 3 times in Belgium, Silverstone 29 times in Britain and Nuremberg 24 times in Germany.
