Thank you all for the excellent and detailed replies. Very much appreciated!
We currently have six nights at Fishing Bridge RV park reserved for next July. But I've considered splitting our Yellowstone stay into Madison campground to put us closer to West Yellowstone and Mammoth areas of the park. Has anyone stayed at Madison? How about Canyon Village?
For our week in Grand Teton we will be staying at Colter Bay Village. Any other favorite places to RV camp in GTNP?
NOTE: We are also hauling our canoe so any recommendations or tips of good paddling spots would be welcome. Along with any favorite out-of-the-way cutthroat streams! ;)
