The fireworks at Coors Field are shot off over the scoreboard in left field. As a result, the best seats for seeing the show are on the first base line in the 200s and 300s sections.

Post-game fireworks at a Rockies game are set off from beyond the scoreboard in LF

For seats down the third base line (like section 143), the overhang will make it difficult to see the show. If you want to be on the 3B side, we recommend choosing a lower row or planning a move to another location before the game ends and before the fireworks begin.
