I summoned people into major cities with my 3 70 locks during the summer festival. i made mint, people paid 5g a piece to my shaman in Shatt standing next to the quest guy, and then I summoned them to silvermoon or org or TB whatever, and they got their 25g for flame or whatever.

was great =)

i know this is useless now, but maybe theres a similar situation available these days.
