Yeah, I discovered those a few years ago when on a driving tour of US. Whole lot cheaper than buying cups of coffee. There are generic brands much cheaper than Vivarin. Besides, if I went inside for coffee, couldn't pass up the danish/donuts that went with it.
One of my favorite drives is the same general path Jodi drove. Stunning! Do it every couple of years. Maybe I'll send her a very descriptive letter next time, highlighting how I CAN do it and she CAN'T anymore.:floorlaugh:
Send her a postcard.
