Outdoor kitchen in Yellowstone (bears)?

We stayed in Madison and cooked on our Webber Grill. No problems.

Your outside refrigerator will be treated like a cooler in bear country. Coolers need to be stored inside your vehicle.

Leaving anything on the table to do with cooking will most likely be confiscated. We volunteered in Rocky Mtn. Nat'l Park and dealt with campers all the time that didn't read the rules. Please do so when you enter the campground. It'll save you frustration.

I recall one instance when an irate camper came banging on our door at midnight wanting to know where his cooler was. We stated that the ranger took it. He demanded that we go to ranger and get it back for him. We told him if he wanted it back he will be the one waking the ranger up! :) He scoffed off and left the next morning. The ranger did return the cooler along with a ticket.

No need to worry about bears. We were there for 5 Days and not a bear to be seen. Not to say there are none there, it is Yellowstone. I only seen one bison on the road outside the campground!

We seen more bears in the Tetons, one of which wandered right through the campground in between the trailers where people had and used outside kitchens. The bears just kept on moving.

Just clean up and put your stuff away!

Cold beans out of a can is good for me.

You will get the rules when you get to the park; you can cook outside, eat outside, but cannot leave anything unattended, even a fork or water bottle. The rangers will ticket you (and, of course, it's for your safety and that of the bears...as they say in Yosemite "a fed bear is a dead bear").
If you go to nps.gov you can probably find a contact e-mail for yellowstone to get an official and current answer before your visit; I have had luck contacting Yosemite with a specific question.

We were in Yellowstone many years ago and someone left a bag of trash near their hard sided travel trailer. We watched a bear come to the camper, rip the bag open, and then proceed to try to get into the trailer. Scratched the side to shreds with his claws. We called a ranger, who arrived within minutes, but by then the camper was a mess. From watching this, I was cautious about even cooking inside our rv.

Camping at Seeley Lake last year and we were told no drinks of any kind could be outside...

When we were in Alaska, every campground had signs about bears. We used our smoker, but cleaned it up and stowed it after every use. Locals were not that cautious as one of our neighbors, an Alaska native, cooked his fresh caught salmon on the grill and then left the skin on the grill and the grill out. I guess they are used to bears. No issues that time though so maybe he knew something we did not.

I read somewhere ya put ammonia in a spray bottle and when yer grill is cool spray it and anything else.

The rule at FB, as I recall, is you can use a grill (charcoal or propane-type) as long as you stow it back inside the hard-sided RV when you are done. No open fires at that campground. And of course you can't leave food out overnight or even scented toiletries.

Not sure what attracted the bison that lumbered into our section at FB one afternoon, but he checked the whole row out before moving on.
