Bikes for trip to Yellowstone and Utah

We're trying to decide if we need to bring our bikes for a trip to Yellowstone and the national parks in Utah. We're not mountain bikers but we do enjoy nice road routes of 20 miles or less. Just wondering if we'll miss the bikes if we leave them at home or if they'll stay on the truck most of the time while we're at the parks.

Most of the responses appear to be from mountain/trail bikers, and you sound like a road biker to me ("nice road routes of 20 miles or less"). Road biking and trailing biking are very different sports.

Although I have both kinds of bikes, I am a road biker at heart and prefer long distance rides on asphalt. Having been to the 5 NP's in S. Utah I would love to return, this time with my 27-speed road bike and do some road work in each park...not interested in riding trails on my trail bike. Each park has good asphalt roads inside the parks. Great scenery, hills, and altitude for a great workout.
