Of course. Raise your right hand and put the other on the Bible and you are good to go. Just tell the law a fellow rider gave you permission to carry. Should be good to go.
On the other hand, if you just keep it hidden on you till you need it, might work too.

Yeah, I wish it was that easy. The chity of Chicago had a handgun ban for 40+ years, until the SCOTUS forced them to overturn the ordinance. So, Chicago then forced people to register handguns at an outragious price BUT you also had to have training with shooting proficiency. However, they maintained the outlaw of gun ranges making it impossible to comply unless you left the city. Then there were reports that they were not honoring the training certs from the border city ranges. So the Ezell case came, and the judge reamed the city, so they tweaked the ordinance where any range had to be at least a ridiculous distance from umpteen categories of current establishments, like schools churches, parks, etc. By the time they plotted it out, no where was possible unless it was in the middle of Lake Michigan. Furthermore, the eventual range would have to pay an enormous licensing fee every year, and deal with all sorts of hardships making it impossible.
So the chity of Chicago just keeps thumbing their noses at the courts and nothing ever happens. Disgusting. Oh, btw, did I forget to mention that all chity alderman and above politians ARE allowed CCW while in the chity, overriding the state laws. Eliteist, Liberal Hypocrits.
