Sand Hallow State Park

Haven't been here yet. Starting to plan the Grand Canyon trip for early June. The Permit Request has to be FAXed in February 1st. The current plan is to camp on the north rim and go down to the river and turn around and come back out the same way. I had wanted to do a rim to rim trip but it is 200 miles by highway from one rim to the the other which makes for a real problem in leaving a car on both sides. There's a bus that runs daily, but it's $80.00 per person one way. If I have a party of 10, that's a lot of money for folks to spend. From the north, will mean we can camp halfway up coming out so the climb will be easier.  And there will be less tourists like us me thinks.
The drive from LA to the North Rim is a 10 hour drive, so this is where Sand Hallow comes in, its 6-7 hours from LA. This or Vegas? Maybe Vegas would be the place to stop coming home.
I hope the usual crew can make it.
