Totally agree. Even here in the NorthEast where it is more of a melting pot I rarely ever saw an Indian before 1990. None even in a college with International students. First worked with a single one in 1994 in a big company. It was only after the dotcom bust that they started being noticeable. Now I see a lot of them.
Started noticing them in very large numbers just in the last 10-15 years. It hit me when I would go to camping sites and stop by the big visitor centers where tourists go and I would see huge Indian families with their extended relatives milling around taking photos, even though they never went hiking or camping.
