I'll be out of town on the 12th but the 26th is fine. Rather than play with the location too much (this gets complicated enough as it is) I think the best bet is to decide on the date and then show up at BBQ's. The food is good enough and the price is right for most of us and the main point is for us to meet and have a good time. Perhaps we should place a call to reserve space in advance, but not if we don't have a firm date. IMO the sooner we decide for sure the more people will be able to really make plans and be there in earnest - at least that is the case for me. My schedule fills up pretty quickly, as I'm sure many people's do...I'd hate to lose a lot of folks that might want to come not be able to because we didn't decide in time.
Also bear in mind if it's at BBQ's - as far as I know they don't seat you until your entire party is present. Is this still the case? If it is, we may want to consider meeting there a little early to make sure we can get our table when it's time. Just something to bear in mind if they still work it that way....
A firm date is what's most important I think....the rest of the details can be worked out once we do that.
