We are an Aussie Family planning a trip in April and have the majority planned except for the trip between Vegas and San Francisco. We have 3 free days,a rented car and wanted to stop at Yosemite NationaL park en route to San Francisco. After reading your forum that the trip via Death Valley is not an option during this time of the year, what do you suggest ? Also what will the conditions be at Yosemite mid April? Is it worth it or should this be bypassed ?
