Weird accomplishment

I accomplished a great feat. When we went to Venice Beach to walk around, I drove to the end of I-10. I have also been to the other end (in Jacksonville). I haven't been on the complete road, but the only parts that are missing are El Paso to San Antonio and Houston to Lafayette. I have also been on almost all of I-40 (some sections many times), only missing the Flagstaff to Barstow section. Anyway, I thought it was kind of cool to have seen both ends to an interstate. Has anyone else accomplished other significantly insignificat feats.
