When I first drove out to the Midwest from the East Coast in June I forgot my sourdough starter. Gasp! I know, how could I? It's like a pet and I was very upset about leaving it and worried it would die before I could get back to MA to get it. Luckily for me I have a very good friend (and former roommate) who was kind enough to feed it for me. About three months later it made the 12 hour trip with me in a cooler in my car in the August heat. I had fed it a few times before leaving MA and lo and behold if it didn't perk right up! The long period of dormancy doesn't seem to have harmed it much. The first time I used it here in MI it doubled on the first feeding and more than doubled with the next. It smells a little different, so perhaps some of the microbes etc have died out. I'll have to make a few batches of bread to see if it tastes or behaves differently.
For my first sourdough loaf in the new place I made a seeded whole wheat sourdough from The Bread Bible. It was a really hearty loaf with a great texture and nutty flavour. I think I'm going to convert my starter to whole wheat next time so I can get even more whole wheat flour in it (I think the recipe is about 50% whole wheat).
I actually let the loaves proof for too long because I was ready to bake them but then had to put them in the fridge at the last minute (alas, life comes before bread), but they seemed to turn out okay anyway. I could detect some off flavours maybe from the dead yeast/overfermenting but my roommate couldn't tell. Overall it turned out well.
