I must have spent half my time at Quartzsite alternating among McDonalds, Carl's Jr, and Burger King. Of the 3 fast food joints, McDonalds has the best public restrooms because it's larger and cleaner. Carl's Jr's restroom was the worst, followed by Burger Kings. In my last day at Q, I stopped into Pilot gas station to check out Dairy Queens and Subway sandwiches. I was pleasantly surprised to find that the Pilot gas station has a really decent restroom that's large and clean. Plus there is also a separate area for taking showers in enclosed and private rooms. I don't know what the fee is for the showers, but it seemed pretty cool.
On another note, it was a new experience for me buying groceries at stores with names such as The Dollar Store and The General Store. I would have never though such stores would sell groceries, as I usually go to Safeway, Trader Joe's, etc. I did in fact cooked food at the campsite with my camping stove on a few occasions. I didn't want anyone to think I ate strictly junk food at McDonalds, haha! Well, let me clarify, I didn't cook meals from scratch. I simply bought semi-frozen foods that were already prepared (ie: Chicken Alfredo pasta, etc), and I only needed to heat it up for 15 minutes.
By the way, I spent a couple hours yesterday cleaning off all the sand and dust from around my van doors, especially the rear doors. For some reason, I noticed most of the Quartszite dust settled on the rear of the roof and covered the top of the back doors. So every time I opened the rear doors, more dust and sand kept seeping through. The side doors also had a bit of dust around the bottom. This was even after I went to the car wash. Dust galore!
