I wrote that for EBJ 92 Nov-Dec 2015. Some of the organizations conducting the raffles may have changed since but most of them are handled by the few organizations listed there and if they're not doing the raffle this year, they might be able to tell you who is. You can also call the state for information. Good luck. With odds as low as they are for many trophy species and top units, some are not much different than a raffle ticket.
It may be possible to get a partial tax deduction for the ticket cost, not that it is a great reason to buy a ticket. It depends on how that particular raffle is structured. Usually, some stays with the 501(c)3 organization to pay overhead because raffles are expensive to run, some goes to conservation done by that organization or the State (usually the State). Sometimes it is the State itself that runs the raffle. You just have to ask.
The bigger tax issue is that the normal cost of what you win is taxable income on your tax return. It may not be such a big deal with a tag, but it will be in those raffles where the prize is a donated hunt with an outfitter. Win a $20,000 sheep hunt and you may end up paying taxes of several thousand dollars, depending on your marginal tax bracket. I don't suppose everyone reports it, but you know that the donating outfitter reports it as a write-off and the organization keeps a record of who won.
