So I just got back from my trip to the Catskills. The Catskills and the Hudson Valley are beautiful. Great photo opportunities abound. That said, I underestimated how difficult it would be travel with a 5 month old while maintaining the freedom to go out and shoot whatever/wherever/whenever.
I did get out to NS Lake and got some nice shots of the family overlooking the Hudson Valley, but wasn't able to visit too many other spots (not that we didn't try: wife too freaked out about the walk along 23A to get to the Kaaterskill Falls trailhead; Hunter Mtn wouldn't let us ride the ski lift to the top with the baby). However, the cabin we stayed at was on a lake and provided a great vista and some wildlife. The blue hole looked really cool, but it was just a bit out of the way to make the trip.
I will post a few of the better photos here by the weekend, but my main reason for posting now is to encourage you to go out to Opus 40 (15 min. west of Saugerties) if you have not already been. What an unbelievable location for all manner of photos. It's amazing for both portraits (especially in the narrow passageways) and landscapes. There are reflection pools and the little museum at the top of the small house has wall to wall to ceiling displays of old quarry tools that make for excellent backdrops or subjects (hooks, chains, saws, chisels, hammers, etc.). Again, if you haven't been do yourself a favor and check it out, and plan to spend some time because there are so many different and cool angles, vertical levels, light contrasts, etc. to utilize.
Anyway, thanks again for your suggestions.
