My Eureka tent is awesome. I think it's called the Solitaire? If you and the wife are looking for a 3-4 man'er, then look at that brand (Apex 3 tent). They make some decent gear, lightweight and lower on the price scale.
I found the key to winning on horses - don't even fucking try. Just find a girl that bets on cute names and follow her lead. You'll get a payout. Not huge, but it worked out every time last week. You can make some serious money playing the exacta box, but you can lose money quickly that way too.
Horse tracks themselves are pretty weird. I was wearing a flannel shirt, rubbing elbows with a group of dudes in seersucker suits and chicks with parasols. Bought a few of them some drinks and they gave me a winning ticket at the end. For the most part, the friendliest gambling arena I've ever been in.
