Would someone kindly explain the Metzius of the situation? The Gemara talks
about Ohel Zaruk, and boxes, so I assume that there there must be something
else here that makes R' RW raise this question.

R' RW:
Rav Sachter's article seems to imply to me that one may NOT exploit certain
heteirim when those heiteirim lack a tradition for doing so. That avoiding
exploiting a certain heter is proof that one SHOULD not exploit that heter. 


Perhaps I wasn't clear. What is the "Heter" that is being exploited to visit
the Rebbe's Ohel? All that was mentioned was that it involves boxes.

P.S. BTW, I've heard an argument similar to R' HS's in the name of a major
Posek regarding wearing modern-day Techeiles: If this is it, explain why the
generations before us were not able to have it?
