Hey guys, I am currently doing the southern tier ACA route. Map two of the pack (which starts in Pheonix and ends in El Paso) I didn't use. I just rode down to Tucson and then caught I-10 and have been on it ever since (now in Lordsburg, NM). Looking at section 3 of the ACA map pack it looks like I will be going through some very desolate areas. Places to camp or get food and water are up to 90 miles apart at some points. My biggest ride so far has been 70, so I am no sure if I can do 90 or not, especially with big hills. I was wondering if it is legal and advisable to just take I-10 all the way through Texas until I get to Austin. It is a far more direct route, and being the interstate I would figure I am bound to find services closer together than following the ACA maps. Please correct me if I am wrong about that. El Paso to Austin would only be 576 miles if I rode I-10 the whole way, and it looks like it'd be 800 or 900 miles to do the same ride the ACA way. What am I missing here?
Edit: I realize that I-10 doesn't go through Austin, but what I propose to do is take I-10 from El Paso all the way to exit 477, at which point I will get off I-10 and take US-290 East the remaining 90 miles into Austin. I'd camp at rest stops and RV parks. Would this be legal?
