I was there (The Springs) until Fall '96 ... Carl was a fixture at Compleat from its Day One. BTW - Prior to being downtown on Tejon Street, Compleat was in the Southgate Shopping Center near the Broadmoor ... Carl was the resident expert on all things then, too. Don't know about later (post '96), but Carl didn't own Compleat ... he was just its brain, brawn, and nerve center. NOTHING he did not know about armor or war gaming!
In the early days, he was weak on cars ... it was always fun to catch him with automotive kit LKFs (Little Known Facts), but he always got even with military trivia!
One more thing ~ either of you remember "Road Apples"?
