The dirt on glass bottle walls

Dale Hodgins wrote:About 15 years ago, I demolished the Glass Castle and mini golf. This touristy failure, was a blight on the landscape of Duncan, British Columbia. Bottles can look nice, in moderation. This place consumed years of the builder's life, in a fruitless effort to create a tourist attraction. The home was destroyed and the business never thrived. A decade later, I finally gave up on selling antique bottles. Only about 100 of several thousand, were sold. They went to the recycling depot.

Couldn't resist looking this up! For anyone else curious:

Kari, I would like to know how your retaining walls have held up over time.  Is this forum still active???

I am also interested in building a retaining wall and just starting my research.
