Cigars Cracking & "Blowing Up"???

[longknocker]

I Store My Cigars At 65-70% RH With My Usual 69% Boveda Packs.. I Smoke Most Of My Cigars On The Golf Course. How Do I Keep My Cigars From Cracking And Blowing Up When They're Stored At 67% And The Humidity Outside Is Anywhere From 30 To 100 ??? Thanks!
