SKIP - I just did a search on GOOGLE for TEXAS HIGHWAY 17 and opened up their road map in SATELITTE VIEW.
I walked the TEXAS 17 road from MARFA to Intersate 10 and did not see anything that stood out. Looks like a well maintained Texas road. Sat View captured cars, trucks, and long trucks using the two lane road.. Only a few small curves shown.. Road has good pull off on both sides for the whole distance.. Lots of eating places in the one or two towns along the way. Gas stations as well...
We use GOOGLE MAPS all the the time when traveling in different places we are not familiar with...
Only took about 5 minutes to zoom down to a good close up view of the road and walk it from MARFA to I10...
Since there is few trees along the way you can get a great view showing other pull outs and parking areas etc...
