Update...

So, with now a month to the wedding, I jumped in and spoke to my to be SIL. They are still finalizing the plans. Just like my brother to leave things to the last minute. They have no time set because they are still looking for a photographer (now?!!) and they can't obtain a permit for the park until the time is known. They only had 18mos notice, haha. Holy moly. Yep, I should have considered all this knowing how my brother operates.
