I know that upon entry into another country by air passports usually get stamped and visas, etc are attached but does this generally happen by land too?

The reason I ask is because most of my travel is to Mexico and have acquired quite a few stamps from different places....when entering by land, specifically at Tijuana, will the passport be stamped as well? And if it's not, is there a place to get it stamped, to have as a 'reminder' of the trip?

Thanks everyone and sorry if this is in the wrong place
