Hi everyone, I live right by a freeway in San Diego, and the traffic noises are driving me insane. I tried planting some trees along the wall to try to deaden the noise, but it's not helping at all. My friends suggested a water fountain, but it sounds so expensive! I would really love to spend more time in my backyard, but it's so difficult when all you hear are constant traffic noises. Are there any inexpensive solutions?? Thank you in advance!
