There are of course other choices for concealed carry besides a typical holster or in a pocket.

Fanny packs, waist packs, purses, bags, packs, various belt pouches, pad folios, shirts and jackets with built-in gun pockets... Each with their own advantages and disadvantages, and some more appropriate in different situations than others. If you're an NRA member, you probably get the NRA Store catalog already, or check out nrastore.com. And of course, other companies will have similar offerings.
