Every year at Mother we have an all-agency ski trip.
This year, we want a responsive site that will work on phones while people are on the slopes. The cell phone coverage there is shit so offline is necessary.
We basically need a schedule of events, phone numbers, etc. Nothing serious and nothing super interactive.
However, we are considering a leaderboard of sorts for some activities, but not a dealbreaker if data is eventually consistent.
Nonetheless, background syncing of sorts and adding to home page is a requirement.
