I'd be immensely grateful if someone here could point me in the right direction for an interesting thread that I saw somewhere on here several months ago which dealt with how an intending citizenship applicant can go about applying to the relevant authority (either Canadian or U.S., or perhaps both?) in order to be able to obtain an official record of one's border crossings to/from the U.S., particularly respecting a full record of one's land-crossings to/from the U.S. With my sincere thanks for all helpful replies.
