As a fellow Minnesotan and a lover of all things "Lake Life". I agree the weekend lake getaways can become self-centered. However, a nice long weekend escape from the daily grind of life focusing on yourself and family is wonderful. The loss of a focus on God during your lake experience doesn't need to be the norm. You can still pray before meals, do a bible study in the evening around the fire, and even attend a local church on Sunday morning. My church has a men's retreat in the Brainerd Lakes area every September. We definitely live the lake life of fishing, drinking, golfing but we also manage to do bible study and attend church on Sunday morning. It can be done! Don't let the lack of an appreciation for God one weekend prohibit you from doing things a bit different on your next trip.
