steveMany aspects make it fun.  
Most rewarding is owning a vintage, upper tier HOF'er card PSA or SGC graded 1 of 1 with none higher - extra special if you were original submitter from raw card.
What I miss most?  Going to a quality card show in person.  Portland, Oregon might as well be on planet Pluto in the card collecting world.
What I don't miss most?  Picking up a nice card at a card show back before grading companies - upon closer inspection at home - the horror - the card has a wrinkle !
