My wife has suggested including Mineral King as part of our next trip to Sequoia; works for me. While researching our first trip I remembered reading about the varmits chewing through radiator hoses, but since we were not going to Mineral King then I did not worry about it. So I've been doing a little mor reading and some of the information indicates that the marmots are a problem in "spring and early summer." Our current plan is to visit in late August or early September. So, are those critters not an issue during that time of year?
