@loisrp @David_LKaplan @alexmeshkin I lived in a dense city for part of the pandemic, there were two walkable walk-up testing sites in my neighborhood. It can be done, but certainly wasn't everywhere (same with other access to testing).
These days, forget about it.
@loisrp@David_LKaplan@alexmeshkin在大流行期间，我住在一个人口稠密的城市，在我的社区有两个可步行的测试点。这是可以做到的，但肯定不是所有地方都能做到（与其他测试渠道一样）。
现在，忘掉它吧。
