During prohibition, how many ways could you have hidden alcohol?

Most of you were not even thought of in the days of prohibition and that includes yours truly. But, if you can think back to the early 20s, when alcohol(in any form)was a law violation to sell nationwide. There were many clever ways that people circumvented the law by hiding and disguising alcohol from the revenuers or G-Men. Question: put on your thinking cap and tell us your clever ways of hiding alcohol back then and would you be successful today with the same hiding procedures?
