As someone else said, if you do your performance calculations and make a note of what obstacles may produce challenging turbulence then you can go to lots of places. If you only go to easy places you won't improve.
You may want to challenge yourself at your home airfield first, in order to be really confident in your handling. That way you will have spare capacity to deal with new places when you go.
Try gently stretching your personal crosswind skill envelope. Try getting it down on the numbers and stopped by a certain marker with less than 1 meter deviation from the centre-line. This is hard and will make you a better pilot. Once you're really on top of the aeroplane and don't need a mile of tarmac to put it down, the world is your oyster.
I fly into farm strips a lot and it feels wierd going somewhere with tarmac and a radio. The farm strips are definitely more satisfying as I've had to work harder to get into them.
Remember to plan well, get a proper briefing over the phone from the strip operator, and then fly 100 hours rather than the same hour 100 times.
