The forum discussion revolves around a supposed discovery related to a plexiglass box lid in Boston. An image was shared, but it was quickly taken down. Some users like erexere and anus905 found similarities with the image. Others like Erpobdelliforme and catherwood express skepticism, suggesting that a plexiglass sheet alone is not conclusive evidence. BINGO emphasizes that the thread is speculative and urges caution in jumping to conclusions. anus905 is particularly interested as they have plans to visit Boston for this purpose. The discussion highlights varying opinions on the credibility of the discovery and the need for concrete evidence before confirming any findings.
