No matter what you think of Jennison, he was a thinker. Here is a report from an officer at the close of the war:

"When he got out of the service he ran a large gambling outfit in Leavenworth. It was a very extensive concern...At any rate, he was scarcely out of the army before he was giving a series of general invitations to army officers to visit what he called his 'gambling ranch.' I went up there once with a bevy of officers to see what sort of place it was and he seemed to have pretty nearly all the upper story of a block in Leavenworth. We were there but a few minutes but long enough to see a great amount of mirrors and cut glass and plate glass and darkies in flunkey costume, and a free lunch, a free bar, liquors and champagne galore, and all kinds of gambling devices apparently in running order with a swarm of tough looking western frontiersmen all spending their money lavishly...." And there you have it, Jennison, the father of the Vagas Comps!
