The smiley face first....In the regular reply mode--not the quick one but the one that says "reply to topic" 1. type your message..2.put the cursor where you want the smile of choice to appear..3. click on the smile of choice, you should see a typed image of the smile appear at the cursor's location...4. go to preview of the message and see if you did it right...if not repeat the process.
If you use the quickie reply mode you can place a smileface at the end of the message but you can't go back and put it in the text.
Now for the vacant space in the I-40 quest... In Shawnee OK-VAN's PIG Stand is a short distance into town from the freeway. Good BBQ stand.. Check out the BIG TEXAN in Amarillo TX, right next to the freeway. 72 oz steak free if you can eat it (and the rest of your dinner) in an hour. Plenty of other choices on the menu. A bit touristy, but a fun stop and change of pace from drive-thrus. I like Dyer's BBQ in Amarillo better, just off the freeway, comfortable, calm, and good BBQ also.
In New Mexico we have tended to stay in Gallup and have yet to find a special place for food there.
In general both Flying J and Petro Truck Stops have decent food stops included in their site.
Lastly In CA, Just east of Barstow, Peggy Sue's 50's Cafe is in Yermo. It is actually at the Yermo exit for I-15..but that is only a couple of miles from the Daggett exit for I-40. I recommend it for burger/diner food. Avoid it on Friday evenings and all day Sunday as it gets buried in the L A to Vegas and return Traffic. (If you have never been in the weekend Vegas traffic on I-15, you haven't experienced CA driving at it's best. It is a 250 mile traffic jam with a 75mph minimum entry speed !!)
