Hi, first time contributer, so here are some questions:)

Could someone please check if I did this speed cam right ?

Also I have added this comercial gym node, but shouldn't I update the overview of the buildings to show that there are 2 different places now ? If so, how ? ( I am using Vespucci on Android)
