Football

Lake effect snow is very moist and therefore very heavy. Buffalo regularly sees a 20" snowfall at some point in the winter. The area covered by a dome is huge; the field itself is 1.32 acres, and with the space on the sidelines and outside the end zones, you're talking about a huge area. If you built a dome there, it would collapse. That much snow weighs thousands of tons.

Folks who live in Buffalo are used to the snow. They can handle it.
