Since we have more folks that would like to go on the tour then I have seats in my car, I propose we break the group in two, three folks plus me in each group.
The first group of 3 will leave the campground with me at around 8:00. We will arrive at Edwards around 9:15 and look around until 12:30.
The second group of 3 will leave the campground around 11:00 and arrive at Edwards around 12:30.
At 12:30 we'll meet at outside Edwards, I'll make sure we all understand where, and the groups will switch. The first group will drive home in the second groups' car and I'll take the second group for a tour in my car.
The second group will look around until about 4:00 and then we'll drive home, rental
Casita in tow. We'll get back to the campground around 5:30.
If you health problems, you should be in the first tour as it will be cooler. I'll let you folks figure out who wants or needs to go when.
