maybe n jail they dont accept letters without return addresses cause maybe ppl try to do shit like that all tha time.... well i guess if u put someone else addy on tha letter.... but then that person would be fucked and we all know karma is a bitch...
If you really need one, you could put a name of a dead person and a random abandoned or for-sale house.
taking drugs on an airplane w/in your country is a eaazy. My last couple of trips I've been carrying just over an 1/8th on me and all I did was use this air tight seal thing that you use for meats and stuff to keep them from going bad and you couldnt smell a thing. Carrying acid is probably easier.. im sure you could get away w/ a whole sheet if you put it in a book or magazine... but thats risky business carrying that much... I mean getting caught w/ an 1/8th of weed is one thing but getting caught w/ that much acid could probably put you in jail for a long while. If your looking at carrying a few just put them in your wallet or maybe in a sock in your bag.
