Narrative:

Flight originated at myf to yum. V66 inbound to ipl. ZLA issued flight following. Descending from 5500 ft to 2000 ft I thought I passed ipl VORTAC and visually saw a VORTAC. I immediately thought it was the bard VOR. ZLA told me to contact yuma approach. I contacted yuma approach. Told them I was over bard. Yuma cleared me straight in to runway 17 and asked me if I had the water tower in sight. I told them no. Yuma approach told me to turn 180 degrees. I complied and saw a single airstrip running east/west. Yuma approach informed me that they didn't have me on radar and to squawk another code. Still negative contact. Yuma approach turned me back to ZLA. By this time I had realized I had not overflown bard but ipl and that I crossed into mexico. No numbers were seen on the runway in mexico. No light signals observed. I headed 360 degrees and contacted ZLA. Squawked the given code and was informed I had crossed into mexico and given a north heading. I turned towards bard VOR and immediately understood what had happened. I skipped a leg on my flight/navigation log.
