Since I needed 150lbs of gravel, I couldn't see buying the pet store kind either at $17/25lbs. I found mine at a nursery/landscaping store for $3 for 25lbs! It was just labeled silica and is very nice looking/natural and was actually cleaner than the few bags I bought at a LFS. -- Kelly mailto:apples at midohio_net ICQ # 9473419 My goal in life...is to be the kind of person my dog thinks I am!
