My brother is starting the season with the Dayton Dragons and I'll be coming up to see him pitch in the next couple of weeks.
(Click for a short plug on my bro!)
How far is the stadium from the airport? Any recommendations on things to do or cigar friendly restaurants/bars?
Dayton Dragons!! Nice. I used to live in Dayton and held season tickets for the time I was there. I got to see some big boys by the name of Austin Kearns and Adam Dunn play before they went to the bigs. The Dayton Airport is small, easy to get into/out of and about 20 minutes to the stadium.
For cigars you should go to
The Wharf in Beavercreek.
For food and libation
The Dublin Pub is within walking distance from the stadium and has outdoor seating for when the weather cooperates and also carries an "alright" assortment of cigars and allows for smoking them. They also carry Guinness on tap and have some of the best live Irish music around. Down the street from The Dublin Pub there is an assortment of restaurants and clubs/bars. There is plenty to keep occupied with and with UD (University of Dayton) nearby there is no shortage of eye candy.
Have fun and good luck to your brother.
