Here’s a real big buck hunter.

An online auction starring Donald John Jr., is raking in the green. During its annual hunting convention in Reno, Nevada, the Safari Club International has been holding an online auction for a “dream hunt” with Donald Trump Jr. and 10 hours before the auction is set to end, the bidding has hit $27,500. The highest bid is by member “Grizzly 333.”

The hunting trip is being billed as the launch of something called the “Hunter Heritage Series” with luxury outfitter Coastal Alaska Adventures, and says, “This year we will be featuring Donald Trump Jr., the number one ambassador for our way of life. … Don Jr and his son will be hosting this year’s hunt along with [Master Guide] Keegan [McCarthy] in Alaska. Join them aboard Alaska’s premiere luxury hunting vessel for a 7-day Sitka black-tailed deer and sea ducks hunt.”

Also up for auction is a Tanzanian leopard hunt (current bid at $27,500), a 10 day “Zambian tuskless elephant hunt” (current bid: $1,300), a cape buffalo hunt in Mozambique (current bid: $7,000), a Russian brown bear hunt (current bid: $4,500 — although an Alaskan brown bear hunt is up to $10,000) and a Cameroon hunt for Lord Derby Eland, Buffalo and Antelope (current bid: $32,500).

The event is sparking outrage from animal-rights groups — with specific ire aimed at the President’s son. “Advertised as a ‘dream hunt,’ this hunting trip will be nothing but a nightmare for the Sitka black-tailed deer and sea ducks who find themselves in the gun sights of Donald Trump Jr. and whoever purchases this sick thrill,” Flocken told CNN in a statement.

Also annoyed is former Beach Boy, Brian Wilson, as the current lineup of the Beach Boys played at the convention on Feb. 5.

Wilson tweeted a link to a petition calling for the band to cancel on Monday, writing that he is “emphatically opposed to” trophy hunting.
