The video is awesome and very emotional. It always makes me feel good to know and learn about such things in different regions - I always loved how people become surprised when they hear we also have a professional league. Unlike basketball and football, there is some kind of a "brotherhood" among hockey fans, especially in countries where hockey is not well-known. It's like bumping into your friend in the spaceship with which aliens abducted you.
That being said, this video does not depict hockey in Kenya, sadly... Playing at a hotel rink? That's even more than "luxury" for Kenyan people. Let alone Africans, even people in rich countries probably could not afford that. Moreover, due to climate, it's impossible to have open or tent-like ice rinks in Kenya. I am not sure if anyone is willing to invest in an indoor ice rink either; the costs are high and almost nobody will play there.
This is the problem with hockey: it's too much dependent on economics. If you want to improve in a city, first you have to make sure that the people there have the money for ice hockey. There is no other solution. Even if you fill the whole city with free ice rinks, they will have to buy gear at some point to keep playing. Unless the world turns upside down, I really can't see Kenya doing much more than that in hockey... There a few countries in Africa with potential though; like South Africa, Algeria etc. You can expect one or two tricks from them.
