Some of my recollections:
1. I don't recall member labor being a "requirement" at the outset, but it quickly became more than just an invitation to pitch in, but rather an exhortation.
2. There was too much "drama" in the weekly communications and not enough description of the the food (such as how to identify which exotic Asian green was which). It just seemed surprising that the various problems Farmer Allan noted weren't things he would be accustomed to dealing with and knowing how to resolve in a measured way.
3. Food quality: It wasn't always pretty, but it was flavorful. I was introduced to greens, especially, that I'd never bothered to try or prepare previously.
4. Food quantity/distribution over the season: I felt like we had to hold out with various forms of garlic for a long time before the veggies starting coming. This would be frustrating to a person just starting with a CSA, but maybe it's also a reassurance that you're not getting "frankenfood," but rather food grown in harmony with nature's cycles.
5. If you want a farm that's "what you see is what you get," then FnL is for you. It's about as far removed from industrial farming as you can get. I can attest that the food literally went directly from the ground to your share bag within a couple days if not the same day -- no warehousing here, which is why week-to-week things were a bit erratic.
6. Geographically, when I was searching, there weren't many CSAs that provided such convenient drop-off points in NW DC. If you care about not wasting a lot of gas to get your share each week, then FnL is one of the "greener" options.
So the bottom line? If you're a first-timer, you might want to wait and see how the 2009 season works out. If you are adventurous and like to be "hands-on" with your food, then FnL provides a good opportunity.
