I visited the HISWA, bone exhibition. RAI as an international expo benefits from a rail, metro and motorway network. The complex looks super modern on the outside. Inside it is the old familiar and elderly halls. The Hiswa probably attracted fewer exhibitors and fewer visitors; it was not busy there. This has advantages for visitors, the exhibitors have time to talk to you about their product. According to 'connoisseurs' the apparently declining visitors' interest is "a sign on the wall" for the HISWA organization.
