| Abstract: | On one-dimensional nearest-neighbour random walks in a space-time random environment are discussed. It is proved that first-arrival time series is a stationary, i.i.d. series corresponding to stationary, and i.i.d. distribution of the random environment. |

| Keywords: | random environments random walks nearest-neighbour stationary |
