Feeling Inspired!

I'm really pleased to say that I've turned a corner this last week. I was lucky enough to go on tour with Noyola and had a great time (some pics to follow later today).
Half way through the tour we were in Houston and could drive home after the show... we had already spent several days travelling, in bars and eating rubbish so I took the opportunity to get out and run. I'm in Texas and it's summer so runs are somewhat hindered by the heat but I was determined to just get out and do what I could. A pretty easy going 4km was enough to make me feel good so I packed my trainers for the second half of our trip.
I surprised myself as I managed to get a couple more runs in on hotel dreadmills while we were away...

They are not usually my favourite thing (as you can see from my drawing) but this week they did have some benefits... Firstly it was a good way to go easy on my knee (there's no camber and they have a bit softer landing than concrete). I was safe in the hotel rather than running around potentially dodgy areas of cities I don't know PLUS they are in air-conditioned comfort so I could run at any time of day. I was making the healthiest choices possible considering that we were on the road and running definitely made me feel energised and healthy.
So basically it seems I have caught the bug again.... I went out for an awesome kayaking session despite the wind yesterday and am looking forward to running again this evening :)

Is it possible to stay healthy on a road trip?

I'm really excited that in a couple of weeks I'm going to get to travel with Paul and his band while they go on tour for a week around Texas. I love to travel and see new places, their music is awesome and they're a great group of guys so I'm looking forward to it.

However there is one aspect of travel over here which I find more difficult than anywhere else in the world. I've travelled quite a lot. I even gave up my job once to go backpacking for a year so I find it surprising that this element of travel still causes me problems.... food and staying healthy on the road.

When I was a backpacker I was younger and I didn't really care what I ate. My body just seemed to deal with everything... though in reality I think I was quite a few lbs heavier in those days too (probably something to do with not caring about what I ate!). In the last couple of years since I started running I've been much healthier. I'm more aware of what I'm putting in my body and often I physically react badly to an unhealthy meal.
In England I have a fairly good grasp on how to stay healthy when I'm away from home but America is totally different. It is the world of fast food, drive thrus and junk food that is guaranteed to make me feel (and look) like a slug.

Although I've learned which are the 'healthier' options on several fast food menus and learned that Subway is my friend, I'm interested to know what you do to stay healthy on the road.
Which is your favourite energy or cereal bar that is fairly balanced nutritionally? I'm a monster if I don't eat for a long stretch of time so I'm hoping these will save me from dashing to the sweet isle when we stop for petrol! I'm also still not running due to my knee so I'm keeping a keen eye on my relatively small calorie intake (boo)
What do you do to avoid eating from fast food restaurants for breakfast, lunch and dinner when on the road for a week? I should clarify I don't think I'm going to be able to chill food or have ice packs for a cooler as I don't know the facilities in each hotel we'll be staying at. If there is anything I can get before I go (online or in Walmart) that would be preferable. Any suggestions for fresher food along the way they could do with being from places like Walgreens rather than dragging the band off to the supermarket while I do a shop ;)
If you have any ideas I appreciate ALL the help and advice you can give.
Thank you
