am i overreacting? or is it bad neighbors

[Hunt Fish Nap]

I would not use any type of poison or desiel but the next time I washed my boat after a fishing trip, I would get a garden hose fertilizer srayer (hose pipe to some people) and fill the container with salt. Then proceed to wash off your driveway using the salt water mixture. Salt water not only is an enemy to boat parts but does an effective job on grass as well. If any repercussions do arise from the dead grass, no evidence of poison or desiel would be present. It would be just an unfortunate occurance from fishing in salt water.
