The Olympics this year are practically down the road from me, but due to having a very small person around, it seemed easier not to buy tickets (having failed to get any in the very first round of sales, along with 90% of other would-be ticket buyers).
Now, I wish I were going to at least one event. The very little one is well under a year, so would be free, but I'd be nervous about possible transportation complications given the usual fragility of the transport network under strain. Still, it makes me think that I should still look into at least one Paralympic event.
In the meanwhile, I can ring bells.
