Yea, yesterdays adventure really showed me the importance of a GPS. I do have a GPS app on my phone that gives me coordinates and tells me how to find our way back...but there was no service out there in the dunes.
After finding our way into the bigger more secluded area of the dunes, my buddy's aluminum sprocket gave out as the hard constant spinning wore the teeth down almost completely, leaving nothing for the chain to grab (Steel sprockets FTW!). And since we were out in the middle of nowhere, surrounded by massive steep dunes, we couldn't walk or push the bike back. We were going to try and double man it on my bike back but riding on steep hills in sand is hard enough with one person, there was little to no way we could of done it with two. So we needed to figure out first how to get back to camp, and then how to get the bike back. We were hoping to flag down a UTV or sand rail that could of strapped the bike down to it but that was more than likely not going to happen.
So as the afternoon approaching and fearing darkness, getting ourselves back was the main goal. I got on one big hill, my brother on another hill nearby and we waved our arms to passing riders. After nearly 45 minutes, some nice folks on quads stopped. Turned out that one of the guys on the quads had a GPS so he was able to tell us the coordinates of the bike. (If it wasn't for him having a GPS, we would of had to try and "remember" where we left the bike to come back for it but in the middle of a sand dunes area 45 miles long by 6 miles wide is near impossible with out GPS coordinates)
A guy on a utility two seater quad gave my buddy a ride back to camp. Once back at camp, we hit up the guys with UTV's at the Vendors who we figured have helped stranded riders before. One guy who worked there said he's done it several times and said he would help and he had a GPS. Only problem was the GPS was having issues and would not accept new coordinates. With only a couple hours of sunlight left, I was thinking the bike was going to sit overnight and get stolen. My buddy then began to ask random people at their camp sites if anyone had a working GPS. With a little luck, a nearby group did. So we gave him the coordinates and he led the way.
So, this trip showed me the importance of a GPS, and now the search for a quality user friendly GPS starts.
