What is the fine-grained topic of the following text: Timing prevented us from taking the scenic Silverton-Durango railroad, but we saw it arrive in Silverton, after which the two of us got caught in different little craft shops (with the wonderful smell of the wood stoves used for heat) during a downpour (it had been sunny only a few minutes earlier…). Only return the topic.
Missed opportunity to take Silverton-Durango railroad and shopping in craft shops during a sudden downpour.
